The MQ-5 gas sensor uses tin dioxide (SnO2) with low conductivity in clean air. It detects combustible gases by measuring changes in conductivity, which increase with gas concentration. This sensor is highly sensitive to butane, propane, and methane, making it ideal for detecting natural gas and other combustible gases.

Features:

  • Sensitive Material: Tin dioxide (SnO2) with low conductivity in clean air.
  • High Sensitivity: Particularly sensitive to butane, propane, methane, and natural gas.
  • Output: Converts conductivity changes into corresponding output signals using a simple circuit.
  • Low-Cost: A cost-effective solution for detecting a variety of combustible gases.

Applications:

The MQ-5 sensor is commonly used for gas leak detection, home safety, and industrial applications involving natural gas, LPG, and methane.
