MQ-7 Carbon Monoxide Sensor

MQ-7 Carbon Monoxide Sensor

 MQ7 CO Carbon Monoxide Coal Gas Sensor detects the concentrations of CO in the air and outputs its reading as an analog voltage. The sensor measures concentrations of CO from 10 to 10,000 ppm.The threshold level for digital output can be easily adjusted using the preset on the board. The MQ7 sensor module can be easily interfaced with Micro-controllers, Arduino and etc.

Specifications:
