Description

Product Overview:

    Sensitive material MQ-6 gas sensors used in clean air, low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-6 gas sensor for propane, butane, LPG high sensitivity, natural gas and has a good sensitivity. The sensor can detect a variety of combustible gas, it is a low-cost sensor suitable for a variety of applications.

Application:                                                                                                   

Suitable for home or industrial on LPG (liquefied petroleum gas), butane, propane, LNG (liquefied natural gas) detection devices. Excellent resistance to ethanol vapor, mist interference.

Features:

  • Using high-quality dual-panel design,with power indicator and TTL signal output instructions
  • The switching signal having a DO (TTL) output and analog 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
  • 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: analog signal output
