Tips: Operating Principle of Air Quality Monitor

Air quality monitor is a kind of meter that can detect formaldehyde, PM2.5, TVOC, temperature and humidity in real time. It is compact, light, exquisite and portable. The air quality monitor are equipped with independent sensors. Through the sensors inside, the pollutant concentration can be accurately measured and the air quality index AQI can be calculated. When the concentration exceeds the limit, the alarm will be given.

The air quality monitor detects the signal of the front-end formaldehyde sensor, PM2.5 sensors, TVOC sensor and temperature and humidity sensor, enlarging the weak signal sensors through the operational amplifier, removing noise interference by the filter circuit, and then through the AD sampling and the high precision processor calculation, and transfer it into the pollutant density value, and display it on the LCD screen.
