MQ7 Carbon Monoxide Gas Sensor Module
MQ7 Carbon Monoxide Gas Sensor Module is used to detect Carbon Monoxide (CO) concentration, it can detect CO-gas concentrations anywhere from 20 to 2000ppm. This sensor has a high sensitivity and fast response time. The module outputs a voltage from 0 to 5V relative to the CO concentration.
Note: PCB dimension, and color may vary slightly.
Note: Power off circuit before connecting/disconnecting the sensor
