Connecting MQ2 Gas Sensor Module to Arduino UNO

2021-05-28· MQ2 Gas Sensor? MQ2 is one of the popular and most used gas sensors in MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon change of resistance of the sensing material when the Gas comes in contact with the material. Using a simple voltage divider network, concentrations of gas can be detected.

Gas Sensor Library for Proteus - The Engineering Projects

2016-05-02· In this Gas Sensor Library for Proteus, I have added eight different Gas Sensors, which are used for detection of different gases. As we all know that Proteus is a simulating software so it won’t be able to detect the gas in real in Proteus. So, that’s why I have placed a Test Pin in each of these sensors so when you make this pin HIGH, then it means the gas is present and if this Test Pin ...

Gas Sensor - Arduino Project Hub

2020-08-21· This gas sensor uses a MQ-2 gas sensor to indicate if there is gas in the area. so the sensor has a threshold value (the threshold value is around the amount of smoke in there is a fire) in that if it goes above it starts alerting people in the vicinity. The alert just shows a red led and starts beeping. This idea is very helpful and is used on a daily basis with the smoke alarms that a lot of ...
