Configure and read out the Raspberry Pi gas sensor (MQ-X)

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, MQ-135, etc.) can also be adapted with a few additional steps. Accessories. All MQ-X sensors return analogue signals, which we can not easily read at the Raspberry Pi.

Configuring MQ-series Gas Sensors and ADS1115 ADCs ...

Dec 29, 2015· Step 5: Breadboard up one of the MQ sensors and the three ADS1115 breakout boards. The boards have a default I2C address of 0x48. Jumper the second board from the Addr pin to Vdd. This will give it the address 0x49. Jumper the third board from the Addr pin to SDA, which will give it the address 0x4a. I used the MQ-2 and connected AO (Analog Out ...

How Can Rpi3B+ read MQ9 Gas Sensor? - Raspberry Pi Stack ...

Oct 31, 2019· @PostarLakogSna, Ah, let me see. Here is my quick and dirty MQ9 Rpi interface summary: (1) MQ9 is a digital guy, can be adjusted by the heating/timing and loading/sensitivity pots/resistors to trigger High logical alarm signal when gas (CO or flammable) leaking, (2) It is not connected to SPI or I2C bus like BMP180 or other sensors, so, no conflict between BMP and MQ …
