Description:
The MQ-135 Air Quality Gas Sensor Module can detect NH3, Benzene and alcohol in the surrounding air. The concentration of the gas is output as an analogue voltage reading.
This sensor can detect concentrations between 10ppm-300ppm (NH3), 10ppm-1000ppm (Benzene), 10ppm-300ppm (Alcohol) and is suitable for portable gas detectors and home safety automation systems.
The module requires 5V (AC or DC) voltage input to operate.
Please read the MQ135 datasheet for more info about the sensor.
