MQ 2 Gas Sensor - IoCT

In order to connect the MQ 2 sensor to the Raspberry Pi, two other sensors are needed. A level converter is needed to take the 5V output signal to a signal and an A/D converter to be able to read the signal in digital form. It is necessary to step the voltage down because a raspberry pi can only read signals at without potential for damage. The A/D converter changes the analog signal ...

MQ2 Gas Sensor - Working Principle & Its Applications

MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide. MQ2 gas sensor is also known as chemiresistor. It contains a sensing material whose resistance changes when it comes in contact with the gas. This change in the value of resistance is used for the detection of gas. MQ2 Gas ...

Interfacing MQ-MQ-2 Smoke / Gas Sensor Module Using ...

2019-11-20· MQ2 is a sensor module that can be used to detect flammable fumes or gases at concentrations between 200 ppm – 10,000 ppm. What is ppm? ppm stands for “part per million”, which is a unit that states the amount or concentration of substances in every 1 million. Almost the same as the unit of percent (%) which means “per cent”.

How to Build a MQ-2 Smoke Sensor Circuit with a Raspberry Pi

Important, it is recommended that you do not obtain the standalone sensor but the whole MQ-2 board. This is because if you buy the standalone sensor, you will have to finish building the whole schematic before you can connect it to the raspberry pi. So that less work is required for integrating this with the raspberry pi, it is recommended that you buy the complete MQ-2 sensor …
