HS5628 type noise automatic monitoring outdoor unitDetailed product description：

One Overview:
The HS5628 noise automatic monitoring outdoor unit transmits noise data in real-time to the monitoring center through all-weather outdoor noise monitoring units installed at various monitoring points, and displays it on the system software of the competent environmental protection department. Display it on the system software of the environmental protection department. The data can be transmitted to the Internet as needed, so that the public can understand the noise pollution situation. It plays a positive role in promoting the city image, enhancing the transparency of urban environmental protection environment management, and strengthening the public environmental awareness.
