MQ 2 Gas Sensor - IoCT

sensor is at working temperature and the platinum wires and SnO 2 form the sensing system. When the gas interacts with the sensor, the heat from the system ionizes the gas. This ionization allows SnO 2 to absorb the gas. This adsorption causes a change in the resistance on the sensor. The output legs then send this resistance as an output signal to the ,5 Connecting the MQ 2 ...

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. One possibility would be to use an Arduino, but we can also …

Smoke Detection using MQ-2 Gas Sensor - Arduino Project Hub

Sensor Pin-out details. How does it Work? The voltage that the sensor outputs changes accordingly to the smoke/gas level that exists in the atmosphere. The sensor outputs a voltage that is proportional to the concentration of smoke/gas. In other words, the relationship between voltage and gas concentration is the following: The greater the gas concentration, the greater the output voltage; The ...
