 Fourth, the selection of noise and dust monitoring station recommendations

When selecting the noise and dust monitoring station, the following factors need to be considered:

1. Clarify the monitoring needs  

   According to the purpose, scope and accuracy requirements of monitoring, select the appropriate monitoring station model and configuration. For example, if you are mainly concerned about the noise and PM2.5, PM10 concentration at the construction site, you can choose the monitoring station equipped with the corresponding sensors; if you also need to monitor the temperature and humidity, air pressure, wind speed and wind direction and other meteorological parameters, you should choose a more comprehensive device.

2. Understand the technical principle  

   Familiarize yourself with the working principle and performance characteristics of different sensors to ensure that the selected monitoring station can meet the actual needs. For example, noise sensors usually use microphones and other acoustic components to calculate the noise level by measuring the propagation speed and amplitude of sound waves, while dust sensors often use optical scattering or laser scattering methods to deduce the concentration of dust by measuring the intensity of scattered light from particles.

3. Consider data transmission and compatibility  

   Choose a monitoring station with stable data transmission and good compatibility for real-time monitoring and data analysis. Modern monitoring stations usually support a variety of communication methods such as 4G, LoRa, Wi-Fi, etc., to ensure that the data can be transmitted in real time to the cloud platform or local server.
