2021-08-06· Your experience with Methane Gas Sensor? Using Arduino. Sensors. frankhgw. August 6, 2021, 10:30am #1. Hello, I am looking at the MQ-4, I am wondering what the sensitivity is. I read the datasheet, "Detecting concentration: 200-10000ppm". But since I'm not familiar with it, it doesn't tell me much. If I am in a cow barn, will I reach 200ppm ? Or (sorry) on a badly ventilated toilet, do I reach ...

Methane Gas Sensor MQ4 (Analog/Digital) - Circuit Electronics

MQ-4 Sensor is highly sensitive to Methane – CH4. Using a MQ sensor and detecting the gas is quite easy. You can either use the digital pin or the analog pin to accomplish this. Simply power the module with 5V and you should notice the power LED on the module to glow and when no gas is detected the output LED will remain turned off meaning the digital output pin will be 0V. Features Power ...
