MQ-7 Carbon Monoxide Detection Sensor Module Previous 
MQ-135 Air Quality Sensor Module is designed for air quality monitoring and hazardous gas detection. It is a sensor module for detecting air quality and pollution-related gases in electronics and robotics projects. The module supports detection of a wide range of gases, including benzene, alcohol, smoke, ammonia, sulfide, and other harmful gases. It uses an internal heater and an electrochemical sensor for gas detection. The module works with a 5V supply and can be connected to Arduino for portable air pollution detection projects. It also includes adjustable sensitivity and an output signal indicator.
