Here we use an MQ2 gas sensor that detects the LPG, Alcohol, Smoke, etc, gases. If there is a gas in the air the resistance between two electrodes of the gas sensor gets increased according to the gas presence. We use node MCU as a microcontroller or a wifi development board that reads the analog values from the gas sensor.

Answer (1 of 2): Sensitive material of MQ6 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exist, The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity t...

30/3/2006· A comparison between adsorption–desorption (A–D) noise models obtained using Langmuir and Wolkenstein theories is presented. This noise is generated by instantaneous fluctuations in the number of the adsorbed molecules, which cause free electron''s density fluctuations in the sensing layer, and consequently a fluctuation in the conductance of the gas sensor.

This tutorial allows the user to know the CO2 and temperature levels in a particular area thanks to the Waspmote Gas sensors kit. Waspmote is an open source wireless sensor platform focused on low consumption modes to allow the sensor nodes ("motes") to be completely autonomous.
