MQ-135 Air Quality Sensor Breakout Board - (AD52063)

Description:

The MQ-135 is a hazardous gas sensor used for air quality monitoring and is suitable for the detection of NH3 (ammonia), NOx, alcohol, benzene, smoke, CO2, etc.

This sensor does not provide absolute values, but simply provides an analog output that must be monitored and compared to threshold values.

Characteristics:

- Working voltage: 5V.

- Pin definition: 1-Output, 2-GND, 3-VCC.

- Quick response features.

- Main chip: MQ-135 Air Quality Sensor.

- Double output: Analog output and TTL level output.

- High sensitivity to Ammonia (NH3), Nitrogen Oxides (NOx), Alcohol, Sulfides, Benzene (C6H6), Carbon Monoxide (CO), smoke and other harmful gases.

- Adjustable sensitivity with potentiometer.

- Detection range: 10-1000ppm.

- Size: 32mm x 22mm x 24mm.

- Good sensitivity to harmful gases over a wide range.

- High sensitivity to Ammonia, Sulphur and Benzene.
