MQ-135 Gas Sensor

The MQ-135 Gas Sensor Module is a professional-grade, Chemiresistive Air Quality monitoring solution engineered for smart indoor ventilation loops, environmental pollution logging stations, and HVAC purification systems. Available at Robotics Bangladesh, this highly sensitive module utilizes an advanced Tin Oxide (SnO2) semiconductor substrate layer that alters its electrical baseline cleanly when exposed to hazardous toxic compounds. Outfitted with an integrated hardware comparator layout, it serves as the ideal cost-effective hardware choice for engineering students, developers, and makers building smart home automation safety switches or localized air hazard metrics.
