5Pcs MQ135 MQ-135 Air Quality Sensor Hazardous Gas Module for Detect Ammonia Sulfides Vapors

Overview:1. The gas sensitive material used in the MQ135 gas sensor is tin dioxide (SnO2) with lower conductivity in clean air. When there is a polluting gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of the polluting gas in the air increases. The change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit.2. The MQ135 gas sensor is highly sensitive to ammonia, sulfides, and vapors, and is ideal for monitoring and harmful gases. This sensor detects a wide range of harmful gases and is a low-cost sensor for a wide range of applications.Features:Good sensitivity to harmful gases over a wide range of concentrationsHigh sensitivity to ammonia, sulfide, , etc.Long life, low costSimple drive circuitApplication:Household air pollution alarmIndustrial air pollution alarmPortable air pollution detectorPackage Included:5 x MQ-135 Air Quality Sensor Hazardous Gas Module
