MQ7 Sensor Module Analog Output - Sensors - Arduino Forum

May 06, 2021 · Hi Everyone! Im having troubles to understand the analog output mq7 module monoxide sensor. And the datasheet doesnt help at all. So here is my question: According to the datasheet this module detects between 10-1000ppm, so if i put the sensor inside of a upside down glass with a candle, this mean that the higher analog value would be match with 1000ppm? I kwon that is a rough …
