Principle of operation

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.

Application of Ozone Sensor

air quality detection

Ozone sensors can be used to detect the concentration of ozone in the air, to provide people with a healthy living environment.

FAQ

Q: What are the characteristics of ozone sensors?

A: Ozone sensors are known for their long service life, cost-effectiveness, and simple test circuit design, making them highly practical and reliable for various monitoring applications.

Q: What is ozone sensor

A: SMT-038 is a semiconductor type gas sensor used to detect ozone components in the environment. The conductivity of the sensor's sensitive material changes with the change in ozone concentration. Using a simple test circuit, this change in conductivity is converted into a signal output corresponding to the change in gas concentration, thereby achieving gas detection. The sensor is packaged in a four-pin metal shell and is a low-cost sensor suitable for a variety of applications.

Q: What does an ozone sensor do?

A: Ozone monitoring is the use of ozone gas detectors to measure the concentration of ozone in the air or in water. These analyzers can calculate ozone levels as needed for industrial applications or can be used to monitor ozone levels regularly to check if air is meeting air quality standards.

Q: How do you calibrate the ozone sensor?

A: The zero calibration can be performed at any time by removing the sensor from the flow housing and exposing it to air for at least 10 minutes. The instrument should give a stable reading at zero or at the single digit ppb level before initiating the calibration.
