MQ9 Gas Sensor Module

MQ9 CO and Combustible Gas Sensor Module

MQ9 Sensor module is useful for gas leakage detection in home, car and industry. It is suitable for detecting LPG, CO, CH4. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. 

The module gives out the concentration of the gases as a analog voltage equivalent to the concentration of the gases. The module also has a on-board comparator for comparing against a adjustable preset value and giving out a digital high or low. MQ9 Carbon Monoxide Gas Alarm Combustible Sensor Module is suitable for Arduino.

Feature MQ9 gas sensor Module

  • Suitable for home or factory gas leakage monitoring devices.
  • Have better sensitivity to CARBON MONOXIDE, METHANE, LIQUEFIED PETROLEUM GAS.
  • High quality dual-panel design, with power indicator and TTL signal output instructions.
  • DO switching signal (TTL) output and AO analog signal output.
  • TTL output valid signal is low. (When the output low signal is on, it can be directly connected micro-controller or relay module.)
  • Analog output voltage : the higher concentration, the higher voltage.
  • Four screw holes, easy positioning.
  • Long life and stability, quick response and resume.

Specification  MQ9 gas sensor Module

  • Input voltage : DC 5±0.2V
  • Power : 150mA
  • DO output : TTL digital 0 and 1 (0.1 and 5V)
  • AO output : 0.1-0.3V (relatively clean), the highest concentration voltage is about 4V.
  • Dimensions : 32(L) * 20(W) * 22(H) mm

Wire connecting method:

  • VCC - positive pole (5V)
  • GND - negative pole
  • DO - TTL switch signal output
  • AO - analog signal output

Package includes

  • 1 x MQ-9 Carbon Monoxide, Combustible Gas Detection Sensor Module
