Description
The alcohol detection module is designed to detect alcohol content in a driver’s exhaled breath. By accurately measuring alcohol concentration, it effectively prevents drunk driving, ensuring road safety and protecting lives and property. The module uses an electrochemical fuel cell-type alcohol sensor, integrated with a temperature sensor for temperature compensation, ensuring measurement accuracy and reliability. In addition, the module is integrated with a pressure sensor to detect the blowing action, further guaranteeing the authenticity of the measurement. The measurement data can be transmitted through a serial port signal, which is convenient for integration with the vehicle's electronic control system.
Application
- Environmental Monitoring: Air quality stations, smart home devices.
- Industrial Safety: Alcohol gas alarms, portable detectors.
- Healthcare: Breath analyzers (alcohol detection).
- Traffic Safety: Alcohol testing for drivers in public transport, logistics transportation, enterprise fleets, private personal vehicles, as well as vehicles in ports, mines, and construction sites.
Features
- High Precision Detection: It adopts advanced electrochemical sensor technology, showing high sensitivity and accuracy to alcohol.
- Fast Response: It can complete the detection of alcohol concentration in a short time to ensure driving safety.
- Stable and Reliable: It has the characteristics of long service life, high precision, high repeatability, and high stability, and is suitable for various complex environments.
- Easy to Install: The module is compactly designed and easy to install, enabling seamless connection with the vehicle.
- Intelligent Control: It supports multiple communication protocols and output methods, facilitating integration with other vehicle - mounted devices.
- Low Power Consumption: With a reasonable design, it has low power consumption and is suitable for long - term operation.

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, but the module will be 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 sales@winsensor.com
Due to high volume of daily incoming emails and time zone difference, we may not be able to reply your emails immediately. But we will reply to your inquiry in 24 business hours.
