What is a Oxygen sensor?

Oxygen is an essential substance for human life activities, so it is extremely important to monitor the oxygen concentration in the environment. It is said that if the oxygen concentration falls below 15%, people will have trouble breathing, if it falls below 7%, it will lead to brain dysfunction, and if it falls below 4%, it will lead to death. Oxygen sensors are required in various scientific and industrial fields, and there are a wide variety of oxygen concentration measurement conditions and systems according to the needs of the fields. A typical example is the zirconia sensor, which is used for product management in semiconductor manufacturing, energy saving in automobiles, and exhaust gas purification.
