STONE HMI Display Application in Air Detector Solutions

Posted on 27 March, 2023 by Micheal Alexander

With the development of the economy and the continuous improvement of living standards, more and more people realize the importance of the environment and health. With the development of household appliances, air quality monitoring is also becoming more intelligent. More and more people choose to use smart air detectors to detect indoor air quality to protect the health of their families.

The Working Principle Of The Air Detector

The air detector is an instrument for real-time detection of formaldehyde, PM2.5, TVOC, and temperature and humidity. Through its internal air detection sensor, it can accurately measure the concentration of pollutants and calculate the air quality index AQI. When the concentration exceeds the standard, it will alarm. Tft lcd display

The working principle of the air detector: the signals of the internal formaldehyde sensor, PM2.5 sensor, TVOC sensor, and temperature and humidity sensor, the weak signal of the sensor is amplified by the operational amplifier, and the noise interference is removed by the filter circuit, and then collected by AD, and A 32-bit high-precision CPU is used to process the calculation, and then convert it into a pollutant concentration value and display it.
