CO Gas Sensor Module (#27931) - RobotShop

The CO Gas Sensor Module uses the MQ-7 gas sensor from Hanwei Electronics. When its internal heating element is activated at V the MQ-7 gas sensor responds to CO gas by reducing its resistance in proportion to the amount of CO present in the air exposed to the internal element. On the sensor module this is part of a voltage divider formed by the internal element and potentiometer R3. …
