The gas-sensitive material used in the DSB07-M10K-J gas sensor is tin dioxide (SnO2), which exhibits low conductivity in clean air. When the sensor is exposed to combustible gases in the surrounding environment, especially propane, liquefied petroleum gas, etc., the conductivity of the sensor increases with the increase in the concentration of combustible gases in the air. By utilizing 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.
Characteristics
* High sensitivity to propane
* Stable performance
* Fast response and recovery time
* Good seismic resistance
