The AZ-Delivery MQ-2 gas sensor as a ready-to-connect module for Arduino and Raspberry Pi
Easy-to-use sensor to measure the concentration of LPG, i-butane, propane, methane, alcohol, hydrogen and smoke in the air. The MQ-2 measures a gas concentration of 100 to 10000ppm and is ideal for detecting a gas leak, as a gas alarm or for other robotics and microcontroller projects.
The MQ series sensors use a small heating element with an electronic chemical sensor. They are sensitive to various gases and are suitable for use in rooms.
The sensor has a high sensitivity and fast response time, but it takes a few minutes to output exact measured values because the sensor has to heat up first.The measured values of the sensor output as an analog value, which can be easily evaluated with a microcontroller.
This sensor is ready for connection to a microcontroller, such as. an Arduino board. An AD converter is also required for use with a Raspberry Pi.
- VCC - 5V power supply
- GND - ground connection
- AOUT - Analog output
- DOUT - digital output
The module has a potentiometer for setting the threshold value. The sensor only outputs a 0 or 1 on the digital pin, depending on whether the set threshold is exceeded.
Attention: The sensor gets warm during operation!
You will find one to test Sample sketch in the download section. Simply upload it to an Arduino board and release some gas near the sensor with a lighter.
