Description
Automotive Alcohol Module is a module designed to detect the alcohol content in the driver's exhaled gas. By accurately measuring the alcohol content, the module can effectively prevent drunk driving behaviors, thus safeguarding road traffic safety and the safety of people's lives and properties. The module adopts an electrochemical fuel cell type alcohol sensor, together with an on-board temperature sensor to realize temperature compensation and ensure the accuracy and reliability of the measurement results. In addition, the module also integrates a pressure sensor, which can realize the blowing action detection to further ensure the authenticity of the measurement, and the measurement data can be transmitted through the serial signal, which is convenient to integrate with the electronic control system of the vehicle.
The automotive alcohol module works based on the electrochemical sensor principle. When the built-in pressure sensor detects the exhaled gas flowing through the pipe at a specific flow rate, the solenoid valve responds quickly and inhales a quantitative sample of the gas, and the sensor activates detection simultaneously. Alcohol and oxygen in the gas undergo a redox reaction within the sensor, releasing an electrical charge to form a current signal. The module detects the current intensity through the circuit, and determines the alcohol concentration after processing by the algorithm, realizing the accurate detection of breath alcohol content.
Application

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
