Description:

MQ135 Gas Sensor module for Air Quality having Digital as well as Analog output. The sensitive material of the MQ135 gas sensor is SnO2, which with lower conductivity in clean air. When the target combustible gas exists, The sensors conductivity is higher along with the gas concentration rising. MQ135 gas sensor has a high sensitivity to Ammonia, Sulphide and Benze steam, also sensitive to smoke and other harmful gases. It is at a low cost and suitable for different applications. Used for family, Surrounding environment noxious gas detection device, Apply to ammonia, aromatics, sulfur, benzene vapour, and other harmful gases/smoke, gas detection, tested concentration range: 10 to 1000 ppm.

Specifications:

Working Voltage: DC 5V

Working Current: 150mA

DOUT: TTL output

AOUT: Analog output

Preheat Time: Over 20s

Features:

Sensitivity to Ammonia, Sulphide, and Benzene steam

With signal output instructions

The TTL output signal is a low level

Analog 0 ~ 5 v voltage output, the higher the concentration, the higher the voltage

The colour is showing pictures.

Sensitive for benzene, alcohol, smoke

Fast response and recovery

Adjustable sensitivity

Signal output indicator

Output voltage boosts along with the concentration of the measured gases increases.

Applications:

Air quality monitor

How to Use:

In the case of working with an MCU:

VCC ↔ 2.5V ~ 5.0V

GND ↔ power supply ground

AOUT ↔ MCU.IO (analogue output)

DOUT ↔ MCU.IO (digital output)
