Measuring Air Quality with Arduino and Gas Sensor

Gas Sensor (MQ-135) The working principle of the MQ135 gas sensor is based on the adsorption of target gases by semiconductor gas-sensitive materials, which changes the resistance value. The sensor contains a sensitive element and a heater, with the sensitive element typically made of metal oxide semiconductor materials, such as tin dioxide (SnO2). When there … Read more
