MQ9 - CO and Combustible Gas Sensor Module

SKU: VM00106

Sale price Rs. 118.64 (excl.18% GST)
Rs. 140.00


This MQ-9 sensor module is a simple to use carbon monoxide (CO) and combustible gas (Methane (CH4), LPG) sensor, suitable for detecting CO, methane and LPG gas concentrations in the air. The MQ-9 can detect CO gas concentrations anywhere from 10 to 1000ppm and combustible gasses from 100-10000ppm. Suitable for home and industrial use, it has fast response and recovery characteristics, long life and reliable stability.

The module features dual signal outputs: An analog output (0V to ~5V), the higher the gas concentration, the higher the voltage, and a digital TTL level output to signal the presence or absence of gas. The TTL threshold is adjustable with the onboard potentiometer.

  • Operating voltage: 5 Volts DC (VCC Pin)
  • Maximum power consumption: 800mW (160mA at 5V)
  • Dual signal output (analog (AO pin) and TTL (DO pin) level output)
  • TTL output signal is normally low, goes high when has is detected. Threshold is adjusted with the onboard potentiometer
  • 0 ~ 5V analog output voltage, the higher the concentration, the higher the voltage
  • Indicator LEDs
  • Power
  • DO (Digital Output On)
  • Detectable CO concentrations: 10-1000ppm
  • Detectable Combustible Gas (CH4, LPG) concentration: 100-10000ppm
  • Dimensions (approximate): 32mm x 20mm x 27mm LxWxH (1.25 x 0.8 x 1.1 inches)
  • Weight: 7 grams
