MQ135 Air Quality Detector Sensor Module for Arduino Projects

Detect harmful gas with this Arduino sensor

This Air quality detector module uses an MQ135 sensor which utilises SnO2 as its gas sensitive material. SnO2 has low electrical conductivity with clean air. So, when surrounded by polluted air, the electrical conductivity of MQ135 will increase and thus changing the electrical conductivity which is converted to corresponding output signal.

MQ135 has a high sensitivity to Ammonia, sulphide, benzene vapor, smoke and other harmful gas. It can detect various harmful gases, making it a cost-effective choice suitable for multiple applications.
