After we dive into the functionality of gas sensors in general, we build a gas alarm with the MQ2 gas sensor that detects smoke and turn on an active buzzer as alarm.

20211116· MQ2 sensors detect methane and butane, for example. MQ138 sensors detect benzene and toluene. At the heart of an MQ2 sensor is a ceramic element coated with tin oxide. The element is heated, causing the tin oxide to emit free electrons. In an atmosphere of air, these electrons combine with oxygen so that no current flows through the sensor. As the atmosphere changes due to the presence …

ICSG017A is a "Gas Sensor" module. The dual signal output (analog output and TTL output). The analog output and increased with the increase of concentration, the higher the concentration higher voltage. Has a very high sensitivity to sulfide, benzene vapor, smoke and other harmful gases. Quick response and recovery characteristics.

Please read the MQ2 datasheet (184k pdf) for more information about the sensor. Connections . Connecting five volts across the heating (H) pins keeps the sensor hot enough to function correctly. Connecting five volts at either the A or B pins causes the sensor to emit an analog voltage on the other pins. A resistive load between the output pins and ground sets the sensitivity of the detector ...
