This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

Those hold the detectors, an MQ-2 gas sensor module, and a thermal conductivity ... To read the sensors and control the air pump, [Markus] employs an Arduino Uno, which unfortunately doesn ...

This module provides an introduction to utilizing a gas sensor with the Arduino. It also demonstrates some warning systems that can be implemented with the sensor. Finally, it provides a sensor ...

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.
