The air quality sensor is a vital component in devices such as air purifiers and fresh air systems, responsible for detecting the concentration of pollutants in the air. The service life of an air quality sensor is an important concern for users.

The service life of an air quality sensor primarily depends on the following factors:

● Sensor Type: There are various types of air quality sensors, including electrochemical, photoelectric, infrared, and ion sensors. Different types have different service lives.

● Sensor Materials: The materials used in an air quality sensor directly impact its lifespan. Generally, materials with strong corrosion resistance result in a longer service life.

● Operating Environment: During use, air quality sensors are affected by environmental factors such as high temperature, high humidity, and strong light. Exposure to harsh environments will accelerate sensor wear.

● Maintenance and Upkeep: Regular cleaning and calibration of air quality sensors can extend their service life.

Based on the above factors, the service life of an air quality sensor is generally between 1 and 5 years. The specific lifespan can be analyzed specifically according to the sensor type, materials, operating environment, and maintenance status.

Below is the typical service life for common air quality sensors:

● Electrochemical sensors: 1-3 years

● Photoelectric sensors: 3-5 years

● Infrared sensors: 3-5 years

● Ion sensors: 2-3 years

When purchasing an air quality sensor, you should choose based on your actual needs and budget. If you have higher requirements for service life, you can select sensors made of materials with strong corrosion resistance and pay close attention to maintenance.

When using an air quality sensor, please note the following:

● Clean the sensor regularly to prevent dust accumulation.

● Avoid placing the sensor in damp or high-temperature locations.

● During use, avoid subjecting the sensor to strong impacts or vibrations.

Through correct usage and maintenance, the service life of an air quality sensor can be extended.
