MQ-2 Gas Sensor Module LPG, propane, hydrogen detection MQ2 for STM32 Development

Out of stock


  • Using high-quality dual-panel design, with power indicator and TTL signal output instructions;
  • The switching signal having a DO (TTL) output and analogue output AO
  • TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module )
  • Analog output voltage with the higher concentration of higher voltage.
  • A gas, natural gas, city gas , smoke better sensitivity.
  • There are four screw holes for easy positioning
  • Has a long life and reliable stability
  • Rapid response and recovery characteristic
  • Input voltage : DC5V Power consumption ( current ): 150mA
  • DO output : TTL digital 0 and 1 ( 0.1 and 5V)
  • AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V
  • Special note: After the sensor is powered , needs to warm up around 20S, measured data was stable , heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal
  • VCC: positive power supply (5V)
  • GND: power supply is negative
  • DO: TTL switching signal output
  • AO: analogue signal output
