· Preheating MQ131 ozone sensor necessary? Get link; Facebook; Twitter; Pinterest; Email; Other Apps February 25, 2011 i understand prior using mq!31 ozone sensor, need preheat 2448 hours, unclear whether have preheat length of time each , every time sensor used. supposed preheat heating element length of time once , you''re able take readings point thereafter or have preheat every time …
· The two important things are: 1. You have to preheat the sensor for 48h at 5V to have consistent result. 2. In order to compute the ppm/ppb, you have to calculate the Rs/R0 and apply the sensitivity curve on it. Just check my lib on https:///ostaquet/ArduinoMQ131driver, you will find useful information in the code ;) Kind regards, Olivier
· I understand that prior to using an MQ!31 ozone sensor, you need to preheat it for 2448 hours, however I am unclear as to whether you have to preheat it for this length of time each and every time the sensor is used. Ar…
Sensor MQ131 requires minimum 48h preheat time before giving consistent results (also called "burnin" 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.
