The DSB07-M10K-S gas sensor utilizes tin dioxide (SnO2) as its gas-sensitive material, which exhibits low conductivity in clean air. When combustible gases are present in the sensor's environment, the conductivity of the sensor increases with the concentration of combustible gases in the air. By employing a simple circuit, the changes in conductivity can be converted into output signals corresponding to the gas concentration. This product is a low-cost sensor suitable for various applications such as combustible gas detection and leak detection.
