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.
