MQ-7 Carbon Monoxide (CO) Gas Sensor Module for Arduino, Raspberry Pi & ESP32

MQ-7 carbon monoxide gas sensor module is a CO detection board for building air monitoring, safety alarms, and environmental sensing projects with Arduino, Raspberry Pi, and ESP32. Based on the MQ-7 sensor, it responds to carbon monoxide in the air so you can track changes in CO concentration for workshop, garage, exhaust, or indoor air quality experiments. This gas sensor module is well suited to robotics, home automation, and prototyping applications where CO detection or warning logic is needed, giving makers a practical way to add carbon monoxide sensing to microcontroller and SBC projects.
