Description

MQ-2 MQ-3 MQ-4 MQ-5 MQ-6 MQ-7 MQ-8 MQ-9 MQ-135 Detection Smoke methane liquefied Gas Sensor Module

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 .

Application:

Suitable for home or industrial hydrogen leak monitoring devices. Can not interfere with ethanol vapor, soot, carbon monoxide and other gases.

Wiring:

VCC: positive power supply (5V)

GND: power supply is negative

DO: TTL switching signal output

AO: analog signal output

NOTE:

After the sensor is powered, need to warm about 20S, measured data becomes stable, heat sensor is normal
