The alcohol detector is a detection instrument used to measure the alcohol content of human exhaled gas. Its core component adopts electrochemical principles and is equipped with a temperature sensor to achieve temperature compensation function. It has the characteristics of high precision, high sensitivity and strong anti-interference ability. At the same time, the pressure sensor is integrated to detect the human body's blowing action, further ensuring the authenticity of the measurement.


Alcohol detection of driver’s driving behavior for online car-hailing, school bus, "two types of passenger cars and one type of vehicles that transport hazardous chemicals, etc." and trucks


  • High precision, high sensitivity
  • Provide UART output mode, with digital interface output, easy to use
  • High stability, excellent anti-interference ability

Technical Support:

Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.

The sensors don't have sleeping mode. It can be set in program if needed.

All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.

The sensor has been fully tested (not calibrated) before leaving the factory. However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.

15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.

Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.

Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.

Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to
