About this item

  • MQ-5 module for lpg, natural gas: SnO2 sensing element heated inside a metal mesh cap
  • Analog output AO rises with gas concentration; digital output DO switches at a level you set
  • 5V DC supply, 4-pin 2.54 mm header (VCC / GND / DO / AO), power and signal LEDs
  • Onboard LM393 comparator and threshold potentiometer, so DO can drive a buzzer or LED with no extra code
  • Two modules per pack; needs warm-up and your own calibration - a prototyping module, not a certified detector
