MQ-7 Carbon Monoxide وحدة حساس

MQ-7 Carbon Monoxide Sensor Module

This is an easy-to-use sensor for detecting Carbon Monoxide (CO), ideal for detecting concentrations of CO in the air. It 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.

Features:

• High sensitivity to carbon monoxide.
• Stable and long life.
