The sensor detects the concentration of LPG, propane and hydrogen in the air, the result can be obtained by measuring the voltage on the analog output. The system is powered with a voltage from 2.5 V to 5 V. It has a digital and analog output, making it compatible with most of the commissioning modules, including Raspberry PiandArduino.

Operating principle:
MQ-2 gas sensor applies SnO2 which has a lower conductivity in the clear air as a gas-sensing material. In an atmosphere where there may be inflammable gases, the conductivity of the gas sensor raises along with the inflammable gas concentration increases. MQ-2 performs a good detection to different inflammable gases such as natural gas, especially sensitive to liquefied gas, propane and hydrogen. Its ability to detect various inflammable gases and lower cost make it an ideal choice of different applications of gas detection.


Features: 

  1. Sensitive for LPG, propane, hydrogen
  2. Output voltage boosts along with the concentration of the measured gases increases
  3. Fast response and recovery
  4. Features boost circuit
  5. Adjustable sensitivity
  6. Signal output indicator
