In an embodiment of the present disclosure, the external air quality improvement device is an air purifier.
In another embodiment of the present disclosure, the external air quality improvement device is an air conditioner.
In yet another embodiment of the present disclosure, the external air quality improvement device is a fan. In yet another embodiment of the present disclosure, the external air quality improvement device is a cooler.
In yet another embodiment of the present disclosure, the external air quality improvement device is a dehumidifier. The safety module is a circuit breaker that is configured to prevent internal short circuits. The safety module comprises a switch over circuit, a relay, a rectifier, and a DC-DC Step-Down Voltage Regulator. The safety module ensures that AC power is not passed to the sensing module, which uses DC power supply. If both AC and DC power sources are connected, the safety module cuts off power supply from one source.
The data stored on the internal storage of the air quality monitoring device (100) is synced with a server for backup purposes.
In yet another embodiment of the present disclosure, the plurality of sensors comprises a plurality of nondispersive infrared sensors. In yet another embodiment of the present disclosure, the server is a cloud server.
In yet another embodiment of the present disclosure, the plurality of air quality parameters measured by the plurality of sensors in real-time include Temperature, Humidity, and concentrations of: Carbon Dioxide (CO2), Particulate Matters, Air Contaminants, Hydrocarbons, Carbon Monoxide (CO), Nitrogen Oxides (NOx), Sulphur Dioxide (SO2), and Volatile Organic Compounds (VOCs). The sensors are reliable and self-calibrating.
In yet another embodiment of the present disclosure, the indicator module comprises a plurality of Light Emitting Diodes (LED’s) of different colours.
In yet another embodiment of the present disclosure, the indicator module (102) is configured to indicate the current status of the indoor air quality as good, poor, unhealthy, very unhealthy, or hazardous. The air quality monitoring device (100) is capable of being operated through both AC and DC power inputs and is capable of switching intelligently for uninterrupted monitoring. A relay module drives the device when it is connected to AC power.
The air quality monitoring device (100) can be operated in a smart mode and a manual mode. In the smart mode, the device (100) controls the power output module only if it is connected to AC power. When the smart mode is turned on, the system decides when to turn on and when to turn off the one or more external air quality improvement devices.
As illustrated in Figure 4, the system decides when to turn on and when to turn off the one or more external air quality improvement device based on a comparison between the measured values of the plurality of air quality parameters and a corresponding recommended range for each air quality parameter. For instance, if the system detects a high level of particulate matter in the indoor air, it turns on an air purifier through the external power output module (103) to reduce the level of particulate matter. Likewise, if the system detects a high humidity level the system reduces the humidity level by turning on a connected dehumidifier through the external power output module (103). Similarly, the system may turn on a fan to improve the air quality by allowing more air to circulate. Once the level of particulate matter, humidity, or any other air quality parameter that was detected by the system as having an abnormal value falls back within the recommended range, the system turns off the power supply to the external power output module (103).
If the smart mode is turned off while the device (100) is running on AC power, any external improvement device that is on is not turned off, thereby leaving the decision of when to turn off the external improvement device to the user. The air quality monitoring system also comprises an application on a handheld device or a wearable device that can be used to communicate with the air quality monitoring device through the communication module in order to receive the measured data on the handheld device or the wearable device. In yet another embodiment of the present disclosure, the application on a handheld device or a wearable device receives the measured data through Bluetooth Low Energy.
In yet another embodiment of the present disclosure, the application on a handheld device or a wearable device receives the measured data through wireless internet.
The system is configured to provide one or more personalized recommendations to the user for improving the indoor air quality. The one or more personalized recommendations are in the form of notifications which are sent through the application on a handheld device or a wearable device. The personalized recommendations are provided by the system based on the measured values of the plurality of air quality parameters. For instance, if the system detects the indoor air quality as being poor with high levels of particulate matter and carbon dioxide, the system recommends the user to open the windows and turn on a fan or an air purifier. Similarly, if the humidity level is high, the system recommends the user to take suitable action such as turning on a dehumidifier.
Figure 5 illustrates a notification mechanism of the system. Any abnormality detected by the system in the measured values of the plurality of the air quality parameters based on a comparison between the measured values and the corresponding recommended ranges is indicated to the user through the indicator module (102), the display module (101), and the alarm module (if the alarm module is kept on by the user). If the system is connected to a communication medium, the data and any customizations implemented by the user are synced with the server, and the one or more personalized recommendations are created by the system, which are subsequently synced with the application on a handheld device or a wearable device and received by the user through the application on a handheld device or a wearable device. If the system is not connected to a communication medium, the measured values are stored on the internal storage of the air quality monitoring device and a reminder is created for the user to turn on a communication medium, which is displayed through the display module (101). In yet another embodiment of the present disclosure, the air quality monitoring device (100) is installed inside a centralized air conditioning system duct without the external power output module (103) and functions as a smart building device to monitor and notify the air quality. The disclosed system is portable and easy to use, and provides personalized recommendations to the user for improving the indoor air quality.
