Description

Features:

The MQ-135 is a semiconductor-based air quality sensor designed to detect a wide range of harmful gases, including ammonia, hydrogen sulfide, benzene vapors, smoke, and other pollutants. It operates through conductivity changes in SnO2 material when exposed to gases. With high sensitivity, low power requirements, and cost efficiency, it's ideal for indoor and industrial air monitoring.
