MQ-4 Natural Gas Sensor Experiment Based on Arduino ...

As a natural gas sensor, the MQ-4 Natural Gas Sensor is a fast and reliable sensor with a high sensitivity to natural gas and methane, also good sensitivity to propane and butane. This natural gas sensor has a long life and low cost and is widely used for gas leak detection. At the same time, two LED lights are used in the project to display the gas concentration: Green light: it means the ...

Interface Arduino with Gas Sensor -

· In this article, we will see how to interface Arduino with the MQ-2 gas sensor. MQ2 gas sensor is used for detecting smoke and some flammable gases like LPG, Methane, etc. It changes its resistance depending on the type of the gas. This principle can be used to raise an alarm based on the concentration of the gas.

conversion to ppm for methane sensor - Arduino Forum

· Some students of mine made a methane sensor with the mq 4. THis is how they tried to convert the analog values to ppm: Since the closest thing to a known methane value that that they had available was straight natural gas coming through the line to a valve in the chemistry lab at the school, they used that as a sample to represent a saturation value (in other words, a million ppm). They read ...

Your experience with Methane Gas Sensor? - Sensors ...

· 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 ...
