==== MQ131 ====

[[https://github.com/ostaquet/Arduino-MQ131-driver/tree/master/datasheet|datasheet]] - [[https://github.com/ostaquet/Arduino-MQ131-driver|esempio utilizzo]] - [[http://wiring.org.co/learning/basics/airqualitymq135.html|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 [[https://github.com/ostaquet/Arduino-MQ131-driver|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.
