What is a co2 sensor in a car

Co2 sensor in a car monitors carbon dioxide emissions from air conditioning in the car

Co2 sensor in a car can not only measure the carbon dioxide concentration in the vehicle exhaust, but also measure the carbon dioxide concentration in the car, which is an important part of the modern automobile emission system. Carbon dioxide is one of the main greenhouse gases, and the amount of carbon dioxide emitted by each vehicle directly affects global climate change and environmental pollution. Therefore, car manufacturers must take carbon dioxide emissions into account when designing vehicle emission systems, and use advanced CO2 sensors to control and monitor carbon dioxide emissions.

Co2 sensor in a car monitors carbon dioxide emissions from air conditioning in the car

The automotive air conditioning control system is a device that cools, heats, ventilates and purifies the air in the compartment. It can reduce the fatigue of the driver, ensure driving safety, and provide a comfortable driving environment for the occupants. It is a measure of whether the function of the vehicle is One of the complete signs.

In a fully enclosed compartment, due to the respiration of the human body, the concentration of carbon dioxide in the compartment will continue to rise. In just over ten minutes, the carbon dioxide concentration in the compartment can reach a state of moderate pollution, causing drowsiness, dizziness, sluggishness, inability to concentrate, etc., and bringing the risk of traffic accidents. After half an hour to an hour, it will reach a state of severe pollution, leading to brain damage, coma and even death!

Therefore, the automotive air-conditioning system needs to inhale fresh air for the compartment through the external circulation in a timely manner to achieve the purpose of ventilation. Among them, the carbon dioxide sensor is essential. It can automatically determine the internal and external circulation status of the automobile air conditioning control system by detecting the carbon dioxide concentration in the automobile.

Working principle

Co2 sensor in a car is a nanotechnology-based gas sensor that uses infrared technology to detect carbon dioxide concentration. When the vehicle is running, the exhaust gas passes through the sensing area of the sensor, and the infrared rays will be sensed by the sensor to measure the concentration of carbon dioxide. The sensor compares the CO2 sensor with a reference oxygen concentration to calculate the actual concentration. These data will be sent to the vehicle’s engine control unit to control engine work adjustments to reduce carbon dioxide emissions.

Advantages of Co2 sensor in a car

Co2 sensor in a car has multiple advantages, including better fuel economy and environmental performance. The use of carbon dioxide sensors can ensure that the concentration of carbon dioxide emitted by vehicles is controlled within the regulatory range, and can help vehicles achieve higher fuel efficiency, thereby reducing emissions. In addition, Co2 sensor in a car can also improve vehicle performance, reduce the harm of exhaust gas to passengers in the car and reduce maintenance costs.
