While the noise pollution comes from different aspect, including vehicle, factory, construction, etc., and this has arisen people’s attention to noise pollution, then request for noise monitor system in residential area have be aroused.
Normally, the noise monitor system is requested in residential area, school, hospital and nursing home where quiet environment is needed. In this system, the noise data will be collected by front-end sensors, then transferred through HELIOS HD210 DTU Series over public 4G/3G/GPRS cellular network to data center to monitor, store, calculate, display and distribute, and there would be an onsite LED billboard to display the real-time decibel value of noise. This will help to people living in that area to lower their voice if the decibel is high.
