The gas-sensitive material used in the DSB01-M10K-S gas sensor is tin dioxide (SnO2), which exhibits low conductivity in clean air. When the sensor is exposed to combustible gases in the environment, the conductivity of the sensor increases with the concentration of the combustible gas in the air. By utilizing a simple circuit, the change in conductivity is converted into an output signal corresponding to the gas concentration. This product is a low-cost sensor suitable for various applications such as combustible gas detection and leakage detection.
