MQ138 Gas Detection Sensor Module

MQ 138 Formaldehyde Aldehydes Gas Detection Sensor

MQ138 Gas Sensor can be used to monitor the concentration formaldehyde gasses. This Module simplifies using the MQ-138 gas sensor by providing digital as well as analog output which can be interfaced to Microcontrollers, Arduino and Raspberry pi.

For the family, the environment of the volatile compounds detection devices, suitable aldehydes, alcohols, ketones, aromatic compounds detected, the gas sensor test concentration range:
  • 1 to 100 ppm benzene
  • Toluene 10 to 100 ppm
  • Methanol 5 to 100 ppm
  • Alcohol 30 to 300 ppm
  • Acetone 10 to 300 ppm
  • Formaldehyde 1 to 10 ppm

Characteristics Of MQ138 Formaldehyde Gas Detection Sensor Module

  • With the signal output LED indication.
  • 2-way signal output (analog output, and TTL-level output).
  • TTL output valid signal is low; (low output signal light, which can be accessed microcontroller IO port).
  • Analog output increases with the concentration, the higher the voltage the higher the concentration.
  • Aldehydes, alcohols, ketones, aromatic compounds with high sensitivity.
  • With a long life and reliable stability.
  • Fast response characteristics.
  • With mounting holes for easy permanent installation.
  • The probe can plug design for easy testing.
