MQ131

datasheet - esempio utilizzo - wiring

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 high concentration of ozone.

This driver is made to control the “naked” Winsen MQ131. The driver is able to pilot the low concentration version and the high concentration version.

To measure the air quality (e.g. pollution), it's better to use the low concentration MQ131 because the high concentration is not accurate enough for low concentration.
