Overview:

Sensitive material MQ-7 gas sensors used in clean air, low conductivity tin oxide (SnO2). High-low temperature cycling detection mode (1.5V heating) carbon monoxide detector, conductivity sensor with the increasing concentration of carbon monoxide gas in the air increases,high-temperature (5.0V heating) cleaning cryoadsorption stray gases. Using a simple circuit to change the conductivity, concentration of the gas is converted to the corresponding output signal. MQ-7 gas sensor of high sensitivity for carbon monoxide, this sensor can detect a variety of gases containing carbon monoxide, is a low-cost sensors for a variety of applications.

Application:

Can be used for home and factory gas leakage monitoring devices, suitable for liquefied petroleum gas, butane, propane, methane, smoke, etc.

Features:

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

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

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

- Analog output voltage with the higher concentration of higher voltage

- There are four screw holes for easy positioning.

- Has a long life and reliable stability

- Rapid response and recovery characteristic

Specifications:

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 .

Wiring:

VCC: positive power supply (5V)

GND: power supply is negative

DO: TTL switching signal output

AO: analog signal output

NOTE:

After the sensor is powered, need to warm about 20S, measured data becomes stable, heat sensor is normal

Package Included:

5 x MQ-7 MQ7 Carbon Monoxide CO Gas Sensor Detection Module
