MQ135 Air Quality Detector Sensor Module
The MQ135 Air Quality Detector Sensor Module is a versatile and reliable sensor for detecting a wide range of airborne pollutants and harmful gases. Designed for integration with Arduino, ESP8266, and Raspberry Pi, it is an ideal choice for IoT-based environmental monitoring, home automation, and smart city projects.
This sensor detects carbon dioxide (CO₂), ammonia (NH₃), benzene, alcohol fumes, smoke, and other harmful gases commonly found in industrial and urban environments. The MQ135 offers dual output signals (analog and digital), enabling easy calibration and threshold setting using the onboard potentiometer.
Thanks to its fast response time, stable performance, and low power consumption, this sensor module is perfect for use in air purifiers, pollution detection systems, greenhouse monitoring, and academic STEM projects.
