TGS822 Alcohol Sensor Module, Ethanol Gas Detector, Serial Output, High Accuracy Alcohol Vapor Measurement for Arduino, Breathalyzer, Industrial Safety Monitoring

The Figaro gas sensor uses tin dioxide (Sno2), a material with low conductivity in clean air, as its gas-sensitive element. When the target gas is present, the sensor's conductivity increases with increasing gas concentration in the air. A simple circuit converts this conductivity change into an output signal corresponding to the gas concentration. The TGS822 sensor is highly sensitive to alcohol and organic solvents and is widely used in alcohol detectors. The TGS823, with similar characteristics, uses a ceramic base and can be used in high-temperature atmospheres up to 200°C.
