Description

This is a simple-to-use hydrogen gas sensor module, comes with the MQ136 gas sensor and circuitry to offer plug and use feature. The sensor is used in gas leakage detecting equipments in home and industry applications. MQ136 gas sensor has high sensitity to Hydrogen sulfide, Low sensitivity for other combustible gas. It is with low cost and suitable for different application.

The figure above shows the connection of MQ sensor to Arduino.

Features:

  • Comes with signal output indicator LED
  • Dual signal output (analog output and TTL level output)
  • TTL output valid signal is low (the output low power signal light is bright, can be connected with the microcontroller IO port)
  • The analog voltage increases with the increase of concentration, the higher the concentration, the higher the voltage is
  • Sensitive to hydrogen sulfide gas
  • Has a long life and reliable stability
  • Fast response recovery characteristics
  • With the installation hole to facilitate the installation of fixed
  • The probe can be inserted into the design, convenient test.
  • Operating Voltage: 5VDC
  • Current comsumption: 150mA
  • Comes with 4 header pins:
    • VCC: 5VDC
    • GND: Ground
    • DO: TTL digital output
    • AO: Analog voltage output
  • After the module is powered, please allow around 20 seconds for the preheating of element in the sensor for stable reading for targeted gas. It will get warm (~50ºC) and that is normal, but it should be burning your hand
  • Product Size (mm): 30(L) x 20 (W) x 28 (H)
  • Weight : 14 g
