Description

MQ136 Gas Sensor monitors the concentration of Hydrogen Sulfide gas. This Module sensor provides a digital and analog output. You can interface the sensor with Microcontrollers like Arduino to get the readings.

Technical Specification:

  • Circuit voltage: 5V±0.1
  • Heating voltage: 5V±0.1
  • Load resistance: can adjust
  • Heater resistance: 31Ω±5%
  • Heating consumption: less than 800mw
  • Sensing Resistance: 30KΩ - 200KΩ (10ppm H2S)
  • Temp: 20℃±2℃ Vc:5V±0.1
  • Humidity: 65%±5% Vh: 5V±0.1
  • Size: 32mm*22mm*27mm (L*W*H)

 Features:

  • Dual signal output (analog output and TTL level output)
  • The TTL output effective signal is low. (The signal light is on when the output is low and can be directly connected to the microcontroller)
  • Analog output 0 ~ 5V voltage, the higher the concentration the higher the voltage.
