How mq135 measures aqi
Web10 dec. 2016 · The MQ135 sensor can sense NH3, NOx, alcohol, Benzene, smoke, CO2 and some other gases, so it is perfect gas sensor for our Air Quality Monitoring Project. When we will connect it to Arduino then it will sense the gases, and we will get the Pollution level in PPM (parts per million). Web9 jul. 2024 · I have just purchased the mq135 gas sensor from ebay ( http://www.ebay.com.au/itm/251930629656 ... EBIDX%3AIT) It has 4 pins - VCC, GND, DO and AO (which I assume means power, ground, digital output and analog output). Apparently the sensor can detect various gases such as:
