What is an ozone sensor

An ozone sensor is a device that converts information such as the composition and concentration of ozone gas into information that can be used by personnel, instruments, computers, etc. According to different detection principles, ozone sensors can generally be divided into three types: ultraviolet, semiconductor, and electrochemical:

UV sensor is a type of sensor that can use photosensitive elements to convert UV signals into measurable electrical signals through photovoltaic mode and photoconductive mode.

Semiconductor ozone sensors use gas-sensitive semiconductor materials. When they absorb ozone, an oxidation-reduction reaction occurs, generating or releasing heat, causing the temperature of the component to change accordingly, resulting in a change in resistance, converting the concentration of ozone into an electrical signal, and measuring the ozone concentration. Measurement.

Electrochemical O3 sensor is based on the principle of electrochemistry, using the measured gas to undergo corresponding oxidation-reduction reactions on the working electrode and counter electrode of the sensor and releasing charges, forming a current through an external circuit, and the current size is proportional to the gas concentration, thereby achieving target gas detection. quantitative measurement.

 

Ozone sensor applications

The application range of ozone sensors is very wide, covering many fields such as people's life, industry, environmental protection and so on. Their applications are introduced below.

1. Air purification

Ozone has a very good effect on air purification. The ozone sensor can quickly detect the ozone concentration in the environment, thereby controlling the working status of the ozone purifier and achieving the effect of purifying the air. In addition, ozone purifiers can further promote air purification by converting ozone into oxygen.

2. Industrial production

In industrial production, ozone sensors can be used to detect the ozone concentration in the air in closed factories, thereby controlling the oxygen concentration and reaction temperature during the production process to ensure the safety and stability of production.

3. Environmental monitoring

Ozone is one of the harmful pollutants in the atmosphere, which is very harmful to the human body and the environment. The ozone sensor can be used to monitor the ozone concentration in the atmosphere in real time, so that timely measures can be taken to reduce the production and emission of ozone.

 

Ozone sensor is a very important sensor, which is of great significance to environmental monitoring and people's health. With the continuous advancement of science and technology and changes in the social environment, the application scope and development prospects of ozone sensors will continue to expand and optimize. We believe that ozone sensors will play a greater role in many fields in the future, thus bringing a better human life and environment.
