Carbon Monoxide CO Gas Sensor (MQ-7)
CHF 9.77

Stock: 1

This is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO concentrations in the air.

The MQ-7 can detect CO concentrations anywhere from 20 to 2000ppm.This sensor has a high sensitivity and fast response time. The sensor's output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.


  • High sensitivity to carbon monoxide
  • Outstanding longlife performance and stability
  • Large electronical singal output


  • Detecting Range: 20 to 2000ppm
  • Sensitivity: R in air/R in typical gas: ≥5
  • Response Time: ≤150s(70% Response)
  • Recovery Time: ≤150s(70% Response)
  • Heating Resistance: 31Ω3Ω
  • Heating Voltage: 5.0V0.2V/1.5V0.1V
  • Heating Power: about 350mW
  • Measuring Voltage: ≤24V
  • Operating Condition:
    Ambient Temperature -20° - +55°C
    Humidity: ≤95%RH
    Environment oxygen content: 21%
  • Storage Condition:
    Temperature: -20° to +70°C
    Humidity: ≤70%RH
