The Analog Carbon Monoxide Sensor (MQ7) is a simple-to-use Carbon Monoxide (CO) sensor suitable for sensing CO concentrations in the air. It can detect CO-gas concentrations anywhere from 20 to 2000ppm. The sensitivity can be adjusted by the potentiometer.
Notice:The new version of analog sensor port pin mapping has been changed as the following two features.Please check the tips for changing sensor cable pin mapping while using the I/O Expansion shield. We will continue to update. For the inconvenience caused, please understand.
