MQ-7 CO Carbon Monoxide Coal Gas Sensor Module



Carbon monoxide (CO) sensor for simple use, suitable for detection of CO concentrations in air.

This is an easy-to-use sensor for detecting Carbon Monoxide (CO), ideal for detecting concentrations of CO in the air.The MQ-7 can detect concentrations in the range of 20 to 2000ppm.

The module has an analog output that comes from the voltage divider that forms the sensor and  a load resistor. It also has a digital output that is calibrated with a potentiometer, this output has a led indicator.

Technical  Specification:

  • Operating Voltage: 5V DC
  • Heating Voltage: 5V (high) and 1.4V (low)
  • Load resistance: adjustable
  • Heating resistance: 33 Ohm
  • Warm Up Time: 60s (high) 90s (low)
  • Resistance Consumption: approx. 350mW
  • Oxygen Concentration: 21%
