The features of the following examples and embodiments can be supplemented or combined with each other without conflict.
The embodiment of the application provides a temperature and humidity sensor module. Referring to fig. 1 and 2, the temperature and humidity sensor module 100 includes a temperature sensor module 10, a humidity sensor module 20, and a heating module 30, and the heating module 30 is used to heat the temperature sensor module 10 and/or the humidity sensor module 20.
In the temperature and humidity sensor module 100 provided in the embodiment of the present application, the heating module 30 may heat the temperature sensor module 10 and/or the humidity sensor module 20, so as to prevent frost or ice from forming on the surface of the temperature sensor module 10 and/or the humidity sensor module 20, thereby improving the detection accuracy of the temperature sensor module 10 and/or the humidity sensor module 20. Therefore, the temperature and humidity sensor module 100 provided in the embodiment of the present application can accurately detect the humidity and the temperature of the environment in the environment where the temperature is lower than zero, and the application range of the temperature and humidity sensor module 100 can be expanded.
When the temperature and humidity sensor module 100 is connected with an external device, such as a vehicle-mounted air conditioner, the accuracy of the temperature value and the humidity value sent by the temperature and humidity sensor module 100 received by the vehicle-mounted air conditioner is high, and the vehicle-mounted air conditioner can accurately judge whether the surface of the evaporator is frosted or frozen according to the received temperature and humidity, so that the evaporator can be subjected to defrosting treatment or anti-frosting treatment in time, the surface of the evaporator is prevented from frosting or freezing, and the heat exchange efficiency of the evaporator is improved. When the temperature and humidity sensor module 100 is connected with the vehicle-mounted air conditioner, the temperature and humidity sensor 100 can be arranged outside the vehicle head to monitor the temperature and humidity of the environment outside the vehicle.
In the embodiment of the present application, the heating module 30 may include at least one of a PTC (Positive temperature coefficient) heating module, a tungsten wire, and a ceramic heating plate.
In one embodiment of the present application, the temperature sensor module 10 and the humidity sensor module 20 may be integrally provided, and the distance between the heating module 30 and the temperature sensor module 10 and the humidity sensor module 20 may be less than 10 cm. Preferably, the distance between the heating module 30 and the temperature sensor module 10 and the humidity sensor module 20 is less than 5 cm. The temperature sensor module 10 and the humidity sensor module 20 may be integrally disposed on a printed circuit board.
In another embodiment, the temperature sensor module 10 and the humidity sensor module 20 may be separately disposed, for example, the temperature sensor module 10 and the humidity sensor module 20 are separately disposed on a printed circuit board. When the heating module 30 is used to heat the temperature sensor module 10, the distance between the heating module 30 and the temperature sensor module 10 may be less than 10cm, and preferably, the distance between the heating module 30 and the temperature sensor module 10 is less than 5 cm. When the heating module 30 is used to heat the humidity sensor module 20, the distance between the heating module 30 and the humidity sensor module 20 may be less than 10cm, and preferably, the distance between the heating module 30 and the humidity sensor module 20 is less than 5 cm.
The two setting modes can ensure that the heating module 30 has higher heating efficiency on the temperature sensor module 10 and/or the humidity sensor module 20, so that the temperature of the temperature sensor module 10 and/or the humidity sensor module 20 is faster, and the situation that the heating module 30 cannot effectively heat the temperature sensor module 10 and/or the humidity sensor module 20 due to the fact that the distance between the heating module 30 and the temperature sensor module 10 and/or the humidity sensor module 20 is longer is avoided.
In an embodiment of the present application, the temperature and humidity sensor module 100 may further include a housing 40, and the temperature sensor module 10, the humidity sensor module 20, and the heating module 30 are disposed in the housing 40. The housing 40 is provided with openings that allow air to pass through the housing 40 and prevent liquids and solids from entering the housing 40. So set up, the gaseous state moisture in the air and the air outside the car can enter into in the shell 40 through the trompil on the shell 40 to the temperature and the humidity of the air in the shell 40 of temperature sensor module 10 and humidity sensor module 20 detectable shell 40 in, because shell 40 and external environment carry out the air exchange in real time, then the temperature and the humidity that temperature sensor module 10 and humidity sensor module 20 detected are the temperature and the humidity of external environment promptly. The openings in the housing 40 prevent liquid and solid from entering the housing 40, and prevent large-sized liquid droplets and solid dust from entering the housing 40 and adhering to the temperature sensor module 10 and the humidity sensor module 20, which may damage the circuits of the temperature sensor module 10 and the humidity sensor module 20. Wherein the size of the opening on the housing 40 may be 0.1mm to 0.8 mm.
The housing 40 may be composed of a first housing 41 and a second housing 42, and the first housing 41 and the second housing 42 are detachably connected. When assembling the temperature/humidity sensor module 100, the first housing 41 and the second housing 42 are first disassembled, the temperature sensor module 10, the humidity sensor module 20, and the heating module 30 are placed inside the first housing 41 or the second housing 42, and then the first housing 41 and the second housing 42 are connected together.
In an embodiment of the present application, the temperature and humidity sensor module 100 may further include a controller 50, the controller 50 is respectively in signal connection with the temperature sensor module 10, the humidity sensor module 20 and the heating module 30, the controller 50 is configured to collect the temperature detected by the temperature sensor module 10 and the humidity detected by the humidity sensor module 20, and control the heating module 30 to heat according to the collected temperature and humidity. The heating module 30 may be controlled by the controller 50 to effectively heat the humidity sensor module 20. Wherein the controller 50 may be a single chip microcomputer.
Referring to fig. 3, the logic for the controller 50 to control the heating of the heating module 30 is as follows:
step 301: the controller 50 determines whether the humidity detected by the humidity sensor module 20 is greater than or equal to a designated humidity value; when the determination result is yes, that is, the controller 50 determines that the humidity detected by the humidity sensor module 20 is greater than or equal to the specified humidity value, step 302 is executed; if the determination result is negative, that is, if the controller 50 determines that the humidity detected by the humidity sensor module 20 is less than the specified humidity value, step 303 is executed;
step 302: the controller 50 determines whether the temperature detected by the temperature sensor module 10 is less than or equal to the first temperature value, and if the determination result is yes, that is, the controller 50 determines that the temperature detected by the temperature sensor module 10 is less than or equal to the first temperature value, step 304 is executed; if the determination result is negative, that is, the controller 50 determines that the temperature detected by the temperature sensor module 10 is greater than the first temperature value, the process returns to step 301.
Step 303: the controller 50 determines whether the temperature detected by the temperature sensor module 10 is less than or equal to the second temperature value, and if the determination result is yes, that is, the controller 50 determines that the temperature detected by the temperature sensor module 10 is less than or equal to the second temperature value, step 304 is executed; if the determination result is negative, that is, the controller 50 determines that the temperature detected by the temperature sensor module 10 is greater than the second temperature value, the process returns to step 301.
Step 304: the controller 50 controls the heating module 30 to start heating.
Wherein the range of the specified humidity value is 40-60%, the range of the first temperature value is-15 ℃ to-10 ℃, and the range of the second temperature value is-10 ℃ to-5 ℃.
Generally, when the humidity of the environment is high, frost or ice is more likely to occur, and when the temperature of the environment is low, frost or ice is more likely to occur. The controller 50 may perform an analysis and judgment according to the humidity detected by the humidity sensor module 20 and the temperature detected by the temperature sensor module 10, so as to control the heating module 30 to heat the humidity sensor module 20. When the humidity of the environment outside the vehicle is greater than or equal to 40% -60%, which indicates that the humidity of the environment outside the vehicle is very high, and the temperature of the environment outside the vehicle is-10 ℃ to-5 ℃, the problem of frosting or icing of the humidity sensor module 20 may occur, and then the controller 50 controls the heating module 30 to start heating the humidity sensor module 20 when judging that the humidity is greater than or equal to 40% -60% and the temperature is-10 ℃ to-5 ℃. When the humidity of the environment outside the vehicle is less than 40% to 60%, it means that the humidity of the environment outside the vehicle is not too high, but when the temperature of the environment outside the vehicle is low, for example, between-15 ℃ and-10 ℃, the surface of the humidity sensor module 20 may be frosted or frozen, and therefore, when the controller 50 determines that the humidity is less than 40% to 60% and the temperature is between-15 ℃ and-10 ℃, the controller controls the heating module 30 to start heating the humidity sensor module 20.
The manner of controlling the heating of the heating module 30 by the controller 50 may enable the heating module 30 to effectively heat the temperature sensor module 10 and/or the humidity sensor module 20. Further, referring again to fig. 3, after step 304, the control logic for the controller 50 to control the heating of the heating module 30 may further include:
step 305: the controller 50 determines whether the temperature detected by the temperature sensor module 10 is greater than or equal to the third temperature value, and if the determination result is yes, that is, the controller 50 determines that the temperature detected by the temperature sensor module 10 is greater than or equal to the third temperature value, step 306 is executed;
step 306: the controller 50 controls the heating module 30 to stop heating, and returns to step 301.
Wherein the third temperature value may range from 5 ℃ to 20 ℃. With this configuration, the heating module 30 can be prevented from continuously heating the humidity sensor module 20, and damage to the temperature sensor module 10, the humidity sensor module 20, and the controller 50 due to an excessively high temperature inside the housing 40 can be avoided.
The temperature sensor module 10 and the humidity sensor module 20 may continuously monitor the temperature and humidity of the environment. The temperature sensor module 10 detects the temperature value of the environment and sends the temperature value to the controller 50. The controller 50 may store the temperature data once in a specified time period, for example, the temperature data may be stored once in 5ms to 10ms, and the stored temperature data may be an average value of the temperatures acquired by the temperature sensor module 10 for N consecutive times, or may be an average value of all the temperatures detected in the specified time period. Similarly, the humidity sensor module 20 detects the humidity of the environment and sends the detected humidity to the controller 50. The controller 50 may store the humidity data once in a specified time period, for example, the humidity data may be stored once in 5ms to 10ms, and the stored humidity data may be an average value of the humidity acquired by the humidity sensor module 20 for N consecutive times, or may be an average value of all the humidity detected in the specified time period. Wherein N can be any integer from 0 to 100, preferably, N is from 5 to 10. Thus, the temperature data and the humidity data stored in the temperature sensor module 10 and the humidity sensor module 20 are more accurate, and the noise interference is reduced. Among other things, the controller 50 may store data in a ROM (Read-Only Memory).
In an embodiment of the present application, the temperature and humidity sensor module 100 may further include a communication module 60, the communication module 60 is electrically connected to the controller 50, the communication module 60 is configured to send the temperature collected by the controller 50 before the heating module 30 heats and the temperature collected by the controller 50 and the humidity collected by the controller 50 to an external device after the heating module 30 heats and when the temperature detected by the temperature sensor module 10 is reduced to a constant temperature. The external device may be a vehicle-mounted air conditioner, and the vehicle-mounted air conditioner receives the temperature and humidity data sent by the communication module 60, determines whether the surface of the evaporator is frosted or frozen according to the temperature and humidity data, and performs frosting prevention or freezing prevention when it is determined that the surface of the evaporator is about to be frosted or frozen.
During the heating process of the heating module 30 and the process of stopping heating of the heating module 30 until the temperature inside the housing 40 is reduced to a constant temperature, the temperature inside the housing 40 is higher than the actual temperature of the environment, so the temperature detected by the temperature sensor module 10 is higher than the actual temperature of the environment in the process, that is, the temperature detected by the temperature sensor module 10 is higher in the process, therefore, the temperature collected by the controller 50 in the process is not sent to the communication module 60, so as to ensure that the temperature data sent by the communication module 60 to the external device is more accurate.
The communication module 60 may be a CAN communication module, and the harness length of the CAN communication module may reach 40 m. Compared with the data transmission with the external equipment by adopting the AD voltage input mode, the data transmission method has the advantages that the interference in the data transmission process can be reduced and the stability of the data transmission is improved by adopting the communication module 60 to carry out the data transmission with the external equipment such as a vehicle-mounted air conditioner.

When the temperature and humidity sensor module 100 is connected to the vehicle-mounted air conditioner, the power supply module 70 may be connected to the vehicle power supply to convert the 12V voltage provided by the vehicle power supply into the rated voltages of the temperature sensor module 10, the humidity sensor module 20, the heating module 30, the controller 50, and the communication module 60.
