What are the requirements for using an air quality monitor?

An air quality monitor is a device used to monitor the concentration of pollutants in the atmospheric environment. Its working principle is to determine air quality by measuring the concentration of various pollutants in the air. The working principle of the air quality monitor mainly consists of the following aspects:

1. Sensor principle: There are many types of sensors used in the air quality monitor, such as chemical sensors, physical sensors and biological sensors. sensors, etc. . These sensors convert the concentration of pollutants into electrical signals.

2. Sampler: The sampler is an important part of the air quality monitor. Its function is to aspirate the air to be detected in the environment to be monitored and pass it to the main sensor for analysis. Samplers are essential to monitor the concentration of various pollutants in the airaccurate analysis.

3. Data transfer: The air quality monitor is required to perform data transfer and send the analyzed data to the data center or users. Data transfer can be done via Wi-Fi, 4G, 5G, zigbee and other wireless communication means.

Therefore, the working principle of the air quality monitor is based on advanced gas analysis technology and data transmission technology for monitoring and analysis.

The air quality monitor has some special requirements for the operating environment:

1. Temperature and humidity: The air quality monitor is more sensitive to the ambient temperature and humidity. In general, the ambient temperature should be between -10°C and 50°C and the relative humidity between 10% and 90%.

2. Electromagnetic Interference: The air quality monitor is a high-precision instrument that is very sensitive to electromagnetic interference in the environmentcaught. It is required that there is no strong electromagnetic interference in the use environment, such as high voltage wires.

3. Environmental pollution: the monitoring results of the air quality monitor must be able to reflect the actual environmental conditions. Therefore, in the operating environment, it is required to isolate the equipment and processes that can lead to air pollution as much as possible.

4. Stable power supply: Generally, the power supply of air quality monitors uses AC or DC power, so the environment is easy to be affected by unstable voltage or large fluctuations. There are certain fluctuation range requirements.
