Ozone detection sensor

Ozone detection sensor adopts the principle of Electrochemical gas sensors to detect and measure ozone concentration in the environment.

The performance indicators of the ozone sensor include response time, sensitivity, accuracy, and stability.

Response time is the time it takes for the sensor to generate a response signal from the time it receives the ozone signal.

Sensitivity is the ability of the sensor to generate a response signal at high ozone concentrations.

Precision is the accuracy of the sensor’s measurement results.

Stability is the stability of the sensor under different conditions, including temperature, humidity, and light.

Generally, ozone sensors consist of a working electrode, a reference electrode, and an electrolyte. The working electrode consists of conductive material and catalyst, and the reference electrode generally consists of silver/silver silver chloride electrode. When ozone gas comes into contact with the surface of the working electrode, a redox reaction occurs, generating a current signal. By measuring the size and change of this current signal, information on ozone concentration can be obtained.
