Introduction

Sensitive material MQ-5 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). When there is the environment in which the combustible gas sensor , conductivity sensor with increasing concentration of combustible gases in air increases . Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-5 gas sensor of high butane , propane, methane sensitivity, methane and propane can be better taken into account. This sensor can detect a variety of combustible gases, especially natural gas , is a low-cost sensor for a variety of applications .aeProduct.getSubject()
   Gas may be used in homes and factories leakage monitoring device suitable for the detection of gas, butane , propane , methane , smoke , etc. ;

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.
  • 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 characteristics

Paramters

  • 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 .

Wiring

  • VCC: positive power supply (5V)
  • GND: power supply is negative
  • DO: TTL switching signal output
  • AO: analog signal output
