API for the DFRobot MQ7 CO Gas Sensor. More...

Detailed Description

• ID: mq7
• Name: DFRobot MQ7 CO Gas Sensor
• Category: gaseous
• Manufacturer: dfrobot
• Connection: analog

The Grove MQ7 Gas Sensor module is useful for detecting Carbon Monoxide (CO) concentrations in the air. It has a detection range of 20-2000 ppm.

For optimum use, it requires calibration after a pre-heat time of 48 hours. See the datasheet for details.
