Oxygen sensor working principle



(1)The working principle of the oxygen sensor is when the oxygen potential in the automobile exhaust pipe is measured by its ceramic sensitive element. By the principle of chemical equilibrium to calculate the corresponding oxygen concentration, to achieve the purpose of monitoring and controlling the combustion air-fuel ratio. 

In order to ensure product quality and exhaust emissions meet the standards of the measuring element. It works similarly to a battery, with the zirconium oxide element in the sensor acting as an electrolyte.


(2)Under certain conditions (high temperature and platinum catalyzed), the difference in oxygen concentration between the inside and outside sides of the oxidized white is used. Generate a potential difference, and the greater the concentration difference, the greater the potential difference. 

Atmospheric oxygen content of 21%, thick mixed combustion after the exhaust gas actually does not contain oxygen. The exhaust gas generated after combustion of the dilute mixture or due to lack of fire contains more oxygen, but still much less than the oxygen in the atmosphere.


(3)At high temperatures and catalyzed by platinum, the oxygen attached to the oxygen sensor is consumed. So there is a voltage difference, thick mixture output voltage is close to 1 V, thin mixture is close to 0 V. 

According to the oxygen sensor voltage signal, control the air-fuel ratio and thus adjust the injection pulse width, so it is the key sensor of electronic control of fuel metering.




Impact of Oxygen Sensors on Environmental Protection


A. Improving the efficiency of emissions control


Oxygen sensors play a key role in emission control by monitoring and controlling automobile and diesel engine emissions, as well as industrial emissions, to improve the accuracy and efficiency of emissions. This helps to reduce air pollution and protect the environment and human health.


B. Optimizing atmospheric monitoring networks


Oxygen sensors can be used for urban air quality monitoring and global climate change studies. By providing accurate atmospheric data, they can help to optimize atmospheric monitoring networks and improve the understanding and prediction of air quality and climate change. This is essential for the development of effective environmental protection measures and policies.


C. Contributing to the improvement of the water environment


Oxygen sensors can be used to monitor water quality. In wastewater treatment and drinking water monitoring, oxygen sensors can help monitor the oxygen content of water to assess the health of water bodies. This is important for the protection and rational use of water resources and the improvement of the water environment.


D. Contribution to global environmental protection


Oxygen sensors, as an important environmental monitoring tool, make a significant contribution to global environmental protection. It provides critical monitoring data and support for environmental protection, driving improvements in emission control, protection and management of the atmosphere and water resources. By promoting sustainable environmental management, oxygen sensor technology has a positive impact on global environmental protection.



Conclusion


1. Future Outlook for Oxygen Sensor Technology


As technology continues to advance, oxygen sensor technology will continue to evolve. In the future, we can expect to see more sensitive, accurate, and durable oxygen sensors. New technologies such as nanotechnology, micro-electro-mechanical systems (MEMS) and biosensors will also be further applied to oxygen sensors, enabling them to monitor and control oxygen levels in the environment more effectively.


2. Implications and challenges for future environmental protection


(1)Although oxygen sensor technology has made remarkable progress, it still faces some challenges in future environmental protection. For example, oxygen sensors may still not be able to provide fully accurate data for certain environmental conditions, such as high temperatures, high humidity, or extreme pH values. 

(2)In addition, while oxygen sensor technology is important for environmental protection, we also need more interdisciplinary collaboration, such as with experts in the fields of artificial intelligence and machine learning, to further improve the performance of oxygen sensors and address their limitations.
