  • GM-102B.png

Summary:

MEMS alcohol gas sensor is using MEMS micro-fabrication hot plate on a Si substrate base, gas-sensitive materials used in the clean air with low conductivity metal oxide semiconductor material. When the sensor exposed to gas atmosphere, the conductivity is changing as the detected gas concentration in the air. The higher the concentration of the gas, the higher the conductivity. Use simple circuit can convert the change of conductivity of the gas concentration corresponding to the output signal.

Feature:

* MEMS technology, Strong construction

* Good shock resistance

* Small sizes and low power consumption

* Fast response and resume

* Simple drive circuit, Long lifespan

APPLICATION

Vehicle Alcohol Test

The picture shows a common "ignition interlock system" with an alcohol detection function in the United States. This lock is connected to the ignition system of the car. Before ignition, the driver must blow air to ensure that the alcohol concentration in the body does not exceed the standard. and the car can start.

Alcohol Detector

Strengthen the punishment of drinking and driving in all the country to reduce the vicious traffic accidents caused by drunk driving. This involves testing a person's alcohol level and using equipment to do the testing. An alcohol detector is an effective tool for measuring the alcohol content in the human body.

FAQ

Here you can learn about the selection guide, common technical problems, packaging, transportation, MOQ, delivery time, etc.

How to use after receiving the goods?

We provide all necessary technical guidance for installation and application by instructions and one-on-one manual service.

Is the Dust Sensor Wired when Shipped?

Laser dust is wired, infrared dust is not wired.

How to Install and Place the Infrared Dust Sensor?

It must be installed vertically. Keep away from artificial air flow such as fans. When used in air purifiers, the front and rear of the fan cannot be installed. Optionally install it on one side of the shell, but keep vents on the shell to ensure that the external air can diffuse in.
