MQ131 Ozone Gas Sensor Module - Cytron Technologies

MQ131 Ozone Gas Sensor Module is a compact board based on the MQ-131 sensor. It is equipped with a very wide range sensitivity to ozone which able to detect ozone concentration up to (10~1000ppb) in ambient air. The tin dioxide (SnO2) is the sensor's sensitive material, has a low conductivity (high resistance) in a clean air environment, and react really good in a presence of ozone. Thus ...

Arduino-MQ131-driver

The MQ131 is a semiconductor gas sensor composed by a heater circuit and a sensor circuit. Heater consumes at least 150 mA. So, don't connect it directly on a pin of the Arduino. Sensor MQ131 requires minimum 48h preheat time before giving consistent results (also called "burn-in" time) There are two different MQ131; a black bakelite sensor for low concentration of ozone and a metal sensor for ...
