Configuring MQseries Gas Sensors and ADS1115 ADCs ...

29/12/2015· I used the MQ2 and connected AO (Analog Out) to the first ADS1115 AO pin (Analog input 0). I''m doing this for testing and software development so I don''t have nine of those MQ sensors dangling around everywhere while I''m trying to debug things. Do I really need to mention to connect Vdd to 5v and GND to ground for both the sensor and the ADS1115 boards? :)

Presenting MQ sensors: lowcost gas and pollution ...

16/02/2018· At this stage, a clarification is needed: as you know, we need to respect the limits of the functions in the component’s document; for example: as for the MQ135, the CO 2 gas curve is defined between 10 and 200 ppm; however, in order to be able to use a gas for which anyone may know its quantity in the air, we supposed the reference curve was valid until 1000 ppm.

You are likely detecting hydrogen (also in farts), which is what your sensor is designed for, and trace other gasses along with the methane. Also, because you are working with a metal oxide semiconductor sensor, you need to let it reach equilibrium in clean gas at at a constant flow and then introduce your fart gas into the gas mixture without changing the flow rate.
