The working principle of 1. electrochemical oxygen sensor

Electrochemical oxygen sensors quantify the oxygen concentration by converting it into an electrical signal through an electrochemical reaction. Specifically, when oxygen molecules in the mixed gas pass through the semi-permeable membrane on the sensor side and enter the inside of the electrolyte, the oxygen is reduced to hydroxide ions (OH) at the cathode, and electrons are generated. These electrons flow back to the anode through an external circuit, forming a closed circuit. The current generated by the reduction and oxidation reactions is directly related to the oxygen concentration entering the electrolyte, that is, the higher the oxygen concentration, the greater the current generated. By accurately measuring and converting this current, the concentration of oxygen in the mixed gas can be determined.

Application of 2. oxygen sensor

Oxygen sensors are quietly changing our way of life and ensuring our safety. It is not only a high-tech product, but also a guardian of our health, safety and environment. The field of industrial safety is a major application of oxygen. Whether it is a petrochemical plant, a steel plant or a mine, oxygen concentration control and detection are essential. The role of the oxygen sensor in these environments is not only to ensure production efficiency, but also to monitor abnormal oxygen concentrations to prevent accidents such as fires or explosions. In the field of environmental monitoring, electrochemical oxygen sensors are like a supervisor, collecting data of oxygen in the air at various monitoring points in the city, and environmental protection workers judge the state of the atmospheric environment from these data. In other applications, oxygen sensors are also actively playing an important role, such as smart home, ecological farming and so on. From these applications, it can be seen that electrochemical oxygen sensors are penetrating into all aspects of our lives, and its application prospects are also very broad. As technology advances, we can expect future oxygen sensors to be smaller, more accurate and more durable.
