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

Description:

The MQ-135 is a hazardous gas sensor used for air quality control and is suitable for detecting 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 with threshold values.

Features:

- Working voltage: 5V.

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

- Fast response characteristics.

- Main chip: MQ-135 Air Quality Sensor.

- Dual 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.

- Sensitivity adjustable with potentiometer.

- Detection range: 10-1000ppm.

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

- Good sensitivity to harmful gases in a wide range.

- High sensitivity to Ammonia, Sulfur and Benzene.
