Things zigbee wireless sensor noise detector (Nanjing IOT intelligent home products)

With further enhance the living and working environment requirements, noise has become an indispensable modern healthy living hard targets. In real life, since the majority of the noise, especially those severely affected the rest of noise, quality of sleep is not open 24 hours a day every day appear, some noise even appear only during certain times of the night, so that environmental monitoring department can not in these noise timely capture recording the event, this aspect led to the noise source escape effective supervision, on the other hand also makes the quality of life of residents declined, social conflicts and dissatisfaction intensified. Facing many noise problems of urbanization, IOT sensing things pioneered full-time radio noise detector WL-WNS-01 in the world, the probe conjugate networking technology, cloud technology, mobile Internet technology, solar technology Noise data 24 hours a day in real-time monitoring of areas of interest for the consumer site, forensics, positioning to provide a guarantee for the environmental protection departments to monitor, track, provide evidence to confirm the noise source. Also by city clouds Things noise detectors and electronic maps combine real-time data published noise of the city, to provide a new basis for decision making for the city administration.
