Automotive sensors are used in air-conditioning fresh air systems

Healthy cars are people's higher requirements for quality of life in the new era.  When the automotive sensor detects the increase of PM2.5 in the air, the data will be displayed on the display screen (voice broadcast can also be realized at the same time), and the system mode will be automatically switched to purify the air quality of the car. 

Among automotive sensors, the CO2 sensor can prevent fatigue driving and monitor vital signs to prevent the danger left behind; when the AQS sensor detects polluted gas, the system can automatically switch between internal and external circulation to keep the cockpit fresh.

Automotive sensors used in other systems

Automotive sensors are the senses of the car. A car is equipped with more than 100 kinds of sensors, and they are helping drivers and passengers to drive the car safely, conveniently and comfortably all the time. Winsen's alcohol sensor has two types: vehicle-mounted and detector. The vehicle-mounted alcohol sensor can be used with the system to create an alcohol lock, so that the driver who is drinking cannot start the car.

Выглядит симпатично, есть регулировка яркости экрана. Данные ppm более менее совпадают с другими моими датчиками (mh-z19). Можно доверять показаниям co2. Температура и влажность не совпадают с другими датчиками, но очень близкие показания (различие в 1 градус, и до 5% влажности. Точность сойдёт для бытового использования.

Automotive Sensor Guide

We have summarized the following questions to help you make better choices.


What alcohol automotive sensors does Winsen have?


According to the detection principle, it is mainly divided into two types: electrochemical type and semiconductor type sensor. Among them, the electrochemical type is mainly suitable for occasions with high precision and low power consumption. The electrochemical types are mainly ME2-C2H5OH-Φ16 and ME2-C2H5OH-13*13 sensors. The semiconductor type is mainly the MQ-3 alcohol sensor.


What is the difference between CO2 automotive sensor MH-V1512A and other CO2 sensors?


The automotive sensor MH-V1512A is dual-channel, high temperature resistant, meets the temperature required by the vehicle, has higher precision, and has a lin output shell.


Does the AQS automotive sensor detect the environment inside or outside the car?


The environment inside the car. When the AQS automotive sensor detects that the air quality in the car is not up to standard, it can automatically switch to external circulation to bring fresh air into the car.


How to calculate the concentration of alcohol in blood?






Can the automotive sensor ME2-CO be used to measure the CO concentration in the underground garage, and the control box will be activated when the concentration exceeds the standard?


Yes, we have experience with such applications.
