Feature

Description

MQ-135 sensor introduction:
The gas sensitive material used with the MQ135 gas sensor is tin dioxide (SnO2), which has a lower conductivity in clean air. When contaminated gas is present in the environment
where the sensor is located, the conductivity of the sensor increases as the concentration of contaminated gas in the air increases. A simple circuit converts the change in conductivity into an output signal that corresponds to the gas concentration.
The MQ135 sensor is highly sensitive to ammonia, sulphides and benzene vapors and is also ideal for smoke and other harmful monitoring. This sensor can detect a variety of harmful gases, is a low-cost sensor for a variety of applications.

Module application:
It is suitable for the detection of harmful gases such as ammonia, aromatics, sulfides, benzene vapor, smoke and other harmful gas detection devices, gas sensor testing range of concentration: 10 to 1000ppm

Electrical performance:
Input voltage: DC5V Power consumption (current): 150mA
DO output: TTL digital quantities 0 and 1 (0.1 and 5V)
DO output: TTL digital quantities 0 and 1 (0.1 and 5V)
Dimension: 32 mm x 20 mm x 22mm

Reminded: After the sensor is powered on, you need to preheat about 20S, the measured data was stable, the sensor is a normal heating, because the internal electric wire, if the hot is not normal.
Wiring:
1. VCC: Positive power supply (5V)
2. GND: connect the negative power supply
3. DO: TTL switch signal output
4. AO: analog signal output

Package Included:
1*MQ-135 MQ135 Air Quality Sensor Hazardous Gas Detection Module

Feature

Description

The gas-sensitive material used in the MQ135 gas sensor is tin dioxide (SnO2) with low conductivity in clean air. When there is a polluting gas in the environment, the conductivity in the sensor increases with the concentration of polluted gas in the air. The change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit.

Specifications:
Size:32* 20* 22mm (L*W*H)
Input voltage: DC5V
Power consumption ( current ): 150mA
DO output: TTL digital 0 and 1 ( 0.1 and 5V)
AO output :0.1-0 .3 V ( relative to pollution ) , the maximum concentration of a voltage of about 4V

Note:
After the sensor is powered , needs to warm up around 20S, measured data was stable, heat sensor is a normal phenomenon , because the internal heating wire , if hot is not normal.
The installation of electronic modules requires basic knowledge and requires a certain electronic professional foundation and hands-on ability. Please purchase carefully!
Manual measurement, with small error. Please check size in detail before purchase.
Real colors may slightly differ from the pictures, as it depends on specific monitor settings and light brightness.

We highly appreciate all customers opinions to improve the selling, also if anything you unsatisfied, please contact us for probable best solution.

Package Includes: 3Pcs
