Abstract
The utility model discloses a monitoring device for temperature and humidity in a greenhouse. The device comprises a singlechip, a temperature sensor, a humidity sensor, a liquid crystal display, an LED (light-emitting diode) and a piezoelectric type buzzer, wherein the temperature sensor, the humidity sensor, the liquid crystal display, the LED and the piezoelectric type buzzer are respectively connected with the singlechip. According to the information on temperature and humidity in a greenhouse detected by the temperature and humidity sensors, data on the temperature and humidity in the current greenhouse can be displayed on a temperature and humidity display unit through the operation processing of the singlechip, and the condition of the temperature and humidity in the greenhouse at the moment can be visually seen; and the temperature and humidity in the greenhouse is conveniently controlled to maintain in an appropriate range; and when the temperature and humidity in the greenhouse do not fall into the designated range, an automatic control unit sends out a signal to drive the LED and the piezoelectric type buzzer to operate. The device has the advantage of simple structure, low cost, easiness in operation and the like.
Description
Technical field
The utility model relates to humiture monitoring device in the greenhouse, is specifically related to the intelligent monitoring device of humiture in a kind of greenhouse.
Background technology
Along with the develop rapidly of modern agriculture, new technology constantly develops input in the agricultural in modern times, and the cultivated area of China's agriculture in greenhouse is also developing expansion rapidly.The growth of all kinds of plants all is in certain environment, to carry out, and in growing process, receives the influence of various factors in the environment, and like temperature, humidity, moisture or the like, what wherein have the greatest impact is temperature and humidity.If temperature and humidity round the clock alters a great deal, it is totally unfavorable to the plant growth.Therefore must monitor and control temperature and humidity, make the growth of its suitable plant, to improve its output and quality.Though the equipment that also have at present some to detect about humiture in the greenhouse, owing to its measuring accuracy is low, and cost height etc. is former thereby be not widely used.
Summary of the invention
To the defective or the deficiency of prior art, the purpose of the utility model is to provide temperature and humidity monitoring device in the intelligent greenhouse that a kind of cost is low, measuring accuracy is high, be convenient to operate.
To achieve these goals, the utility model adopts following technical scheme to be achieved:
Temperature and humidity monitoring device in a kind of greenhouse; It is characterized in that; Comprise single-chip microcomputer, temperature sensor, humidity sensor, LCD, LED light emitting diode and piezo buzzer, said temperature sensor, humidity sensor, LCD, LED light emitting diode and piezo buzzer are connected with single-chip microcomputer respectively.
Said single-chip microcomputer adopts the AT89S52 single-chip microcomputer.
Said temperature sensor adopts the DS18B20 temperature sensor.
Said humidity sensor adopts the HM1500LF humidity sensor.
The device of the utility model detects the information of temperature and humidity in the greenhouse according to temperature and humidity detecting unit in the greenhouse; After the single-chip microcomputer calculation process; In the greenhouse, demonstrate the data of temperature and humidity in the current greenhouse on the humiture display unit; Thereby can see the temperature and humidity situation in greenhouse this moment intuitively; Temperature and humidity with in the convenient control greenhouse maintains in the suitable scope, and when temperature and humidity in the greenhouse is not in specified scope, sends signal driving LED light emitting diode and piezo buzzer work by automatic control unit.Temperature and humidity detection, demonstration and warning device have simple in structurely, with low cost in the greenhouse of the utility model, are convenient to advantages such as operation.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Embodiment
Referring to Fig. 1; The temperature and humidity monitoring device comprises single-chip microcomputer, temperature sensor, humidity sensor, LCD, LED light emitting diode and piezo buzzer in the greenhouse of the utility model, and said temperature sensor, humidity sensor, LCD, LED light emitting diode and piezo buzzer are connected with single-chip microcomputer respectively.Single-chip microcomputer wherein adopts the AT89S52 single-chip microcomputer, and temperature sensor adopts the DS18B20 temperature sensor, and humidity sensor adopts the HM1500LF humidity sensor.
Temperature sensor DS18B20 and humidity sensor HM1500LF can be real-time the detection greenhouse in the situation of temperature and humidity, and send detected temperature and humidity information to single-chip microcomputer with analog voltage signal, further to handle.
The information of temperature and humidity in the greenhouse that the humiture detecting unit is sent in the real-time reception greenhouse of single chip computer AT 89S52; And these information are handled fast and accurately; According to the temperature and humidity scope that the different crops different developmental phases sets, the control signal after the output of humiture display unit and alarm unit is handled in the greenhouse then.
Control signal after the processing that the real-time reception automatic control unit of LCD12864 LCD is exported, and on display, demonstrate the information of temperature and humidity in the current corresponding greenhouse.
The workflow of the utility model is as follows: after system's power supply and program initialization; DS18B20 temperature sensor and HM1500LF humidity sensor begin to detect the temperature and humidity in the greenhouse, and with the form output of detected humiture information with aanalogvoltage.The voltage signal of being exported by DS18B20 temperature sensor and HM1500LF humidity sensor is sent into the A/D mouth of single-chip microcomputer; After carrying out the analog digital conversion; Curvilinear function according to the voltage that sets in the program and temperature, voltage and humidity; Calculate temperature and humidity in the greenhouse, and this humiture information is sent to by display, on this display, show temperature and humidity in the current greenhouse.If temperature or humidity have surpassed the scope that sets in the greenhouse, then the control signal sent LED light emitting diode and piezo buzzer of automatic control unit makes its warning.So detection of reciprocation cycle, thus realize that real-time detection, state to temperature in the greenhouse show and warning.
Used electronic devices and components are commercially available known product in the device of the utility model, and those skilled in the art can realize the connection of each electronic devices and components according to the application's technique effect.
