Vehicle CO Detection
Let every driver take a rest in peace
If you rest in a closed car while parking and idling, shortness of breath may occur over time. If you sleep with the air conditioner turned on in the cab or with a truck heater, it is easy to inhale too much carbon monoxide and cause poisoning and loss of consciousness. In severe cases, life will be lost.
Winsen integrated CO detection inside the truck heater to detect the CO concentration in the vehicle while heating. Make the driver safer and more at ease during long distances.
In addition to being integrated into the heater, the Winsen sensor can also be used as a car charger CO detector, which is powered by the vehicle power supply. Real-time monitoring of CO in the car during idling and driving to ensure your travel safety.
Effectively prevent spontaneous combustion accidents in vehicle
Spontaneous combustion accidents of electric buses and hybrid buses are mostly caused by the failure of power battery packs. Therefore, the power battery plays a vital role in the safety of the vehicle. In addition to effective fire protection measures for vehicle battery systems, people also place their hopes on high-performance fire smoke detection technology. Through the application of high-tech fire smoke products in its vehicle field, its disasters can be detected early, controlled and eliminated in the early stage.
At present, the detection technology combining gas sensor and traditional fire smoke sensor has been widely used in the field of vehicle fire smoke detection. In the early detection mode of temperature and smoke sensor, because the judgment of smoke mainly relies on physical methods, that is, the scattering of light by the smoke particles or the blocking and adsorption of ions inside the detector makes the smoke detector alarm. And dust and water mist, which are very similar to smoke, also make the detector alarm, which produces false alarms. After in-depth research and discussion on automobile fire detection technology, through the analysis of carbon monoxide, the unique chemical component of smoke generated by vehicle batteries, the false alarms caused by interference signals such as dust and water mist are completely filtered out. On this basis, the carbon monoxide plus smoke detection technology has gradually become the mainstream of monitoring car battery fires with its unique advantages.
Importance of carbon monoxide (CO) parameters in fire smoke monitoring:
When a fire occurs, the gas combustion products are mainly CO and CO2, and CO is a unique sign of very early fires. Because the content of CO in the air is generally very low, in the process of fire, CO is produced by the incomplete combustion of almost every substance, especially in the smoldering stage of the fire, from the fire to the violent combustion of CO undergoes a regular change process from small to large, and then gradually decreases, and CO has less dense than air, it is easier to float earlier to achieve early warning. Therefore, CO is suitable for early detection of fire, which is very important for capturing fire occurrence information at an earlier time, and is also a very important monitoring parameter in fire smoke detection.
Mature vehicle fire and smoke alarm system solutions
Optical smoke sensor and CO sensor (recommended model: sensor ME2-CO, ME2-CO-Ф14×14 sensor module: ZE16-CO) is the core of vehicle smoke alarm system, mainly used in hybrid and pure electric commercial vehicles. It is mainly used to monitor the spontaneous combustion of buses and long-distance buses due to battery short circuit or circuit failure. It is generally installed on the top and side of the battery compartment of commercial vehicles. According to the size of the lithium battery compartment, 2-4 batteries are installed, and the maximum configuration is 8 batteries to achieve ultra-high precision and ultra-fast alarm capability.

It make detection by method of cycle high and low temperature, and detect CO at low temperature (heated by 1.5V).The sensor’s conductivity gets higher along with the CO gas concentration rising. At high temperature (heated by 5.0V),it cleans the other gases adsorbed at low temperature. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit.
