20180611· Arduino board I’m using is Arduino UNO. I have also designed an LPG Gas Leak Detect using Arduino using this MQ2 Sensor. So, let’s get started with How to design Smoke Detector with Arduino MQ2 Sensor. Smoke Detector with Arduino MQ2 Sensor. First of all, we need to connect some jumper wires between Arduino and MQ2 smoke sensor shield.

How to configure any MQ sensor and read it out with the Pi will be shown on the example of the Raspberry Pi gas sensor MQ2 in this tutorial. All other sensors (MQ3, MQ135, etc.) can also be adapted with a few additional steps. Accessories. All MQX sensors return analogue signals, which we can not easily read at the Raspberry Pi. One possibility would be to use an Arduino, but we can also …

Working with Gas Sensor. Using an MQ sensor it detects a gas is very easy. You can either use the digital pin or the analog pin to accomplish this. Simply power the module with 5V and you should notice the power LED on the module to glow and when no gas is detected the output LED will remain turned off meaning the digital output pin will be 0V LOW). Remember that these sensors have to be kept ...
