Product Description

MQ-9 Sensor

Sensitive material MQ-9 gas sensor is used to clean the air in the lower conductivity of tin dioxide (SnO2). Detection method using low temperature cycling (1.5V heating ) to detect carbon monoxide, conductivity sensors with carbon monoxide in the air increased with increasing gas concentration , spurious adsorption at high temperatures (5.0V heating ) detection of combustible gases methane, propane and cryogenic cleaning gases. Simple circuit can be used to change the conductivity , concentration of the gas is converted to the corresponding output signal. MQ-9 high gas sensor for carbon monoxide, methane , liquefied petroleum gas sensitivity , the sensor can detect a variety of gases containing carbon monoxide and flammable , is a low-cost sensors for a variety of applications .

Module Applications:

Suitable for home or factory gas leakage monitoring devices, Monitoring devices suitable for carbon monoxide and other combustible gases ,Carbon monoxide can be tested 10 to 1000ppm CO, Combustible gas range 100 to 10000ppm

Module Features :

1. Using high-quality dual-panel design, with power indicator and TTL signal output instructions.

2. The switching signal having a DO (TTL) output and analog output AO.

3. TTL output valid signal is low . ( Low-level signal when the output light can be directly connected to the microcontroller or relay module ).

4. The higher the voltage of the analog output voltage with concentration higher.

5. For the carbon monoxide detector has good sensitivity.

6. There are four screw holes for easy positioning.

7. Product dimensions : 32 (L) * 20 (W) * 22 (H)

8. Has a long life and reliable stability

9. Rapid response and recovery characteristics.

Electrical properties:

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

Special 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 .
