a noise monitoring system is designed based on Internet of things( IoT). The system consists of monitoring terminal
regional center node and management center. Monitoring terminal integrates MCU module
noise sensor module
GPS module
wireless communication module and so on. Noise sensor module is used to noise data
and GPS module is used to obtain noise source location and these information is uploaded to regional center node which used for receiving datas in mornitoring terminal and uploaded to the server through wireless transmission network.Monitoring center publishes noise datas and draws noise maps. Experimental results show that the system can accurately measure in real time and transmit data
and can be used as the basis of control noise pollution.
