Cat No: SGS-LJX-0007 Datasheet
Product Name: Combustible Gas Sensor, 300–10000 ppm (methane, propane), Bakelite, metal cover
Quantities: - +
| Detailed Description | The combustible gas sensor uses tin dioxide (SnO2), a gas-sensitive material with low conductivity in clean air. When combustible gas is present in the sensor's environment, the sensor's conductivity increases with the concentration of the combustible gas in the air. A simple circuit can convert this conductivity change into an output signal corresponding to the gas concentration. The MQ-5 combustible gas sensor has high sensitivity to butane, propane, and methane, and also provides good sensitivity to methane and propane. This gas sensor can detect a variety of combustible gases, especially natural gas, making it a low-cost sensor suitable for a wide range of applications. |
