MQ-6 Gas Sensor Pinout, Specs, Equivalent, Circuit & Datasheet

2018-04-20· Basically we need to look into the (Rs/Ro) VS PPM graph given in the MQ-6 datasheet, and also shown below. The value of Ro is the value of resistance in fresh air and the value of Rs is the value of resistance in Gas concentration. First you should calibrate the sensor by finding the values of Ro in fresh air and then use that value to find Rs using the formulae: Once we calculate Rs and Ro we ...

How to Use MQ-4 Methane Gas Sensor | Microcontroller Tutorials

2020-09-11· MQ-4 Methane Sensor Overview. At the heart of the MQ-4 is a heater and electrochemical sensor. When the target gas enters the membrane and reaches the sensor, it undergoes a redox reaction which creates current. This current is stronger for sensors at specific gases. In the case of the MQ4, it’s more sensitive to methane, butane and propane.
