The WS302 is a sound level sensor with a built-in microphone.
WS302 can not only measure a wide range of noise levels and send different types of sound level values via LoRaWAN® network, but it also supports multiple weighting measurements for different application scenarios.
Combined with our Telemesure.net IoT cloud solution, users can manage all their sensor data, record threshold alerts and receive real-time noise level exceedance alarms via a browser or remote mobile device.
The WS302 can be used in intelligent buildings, such as shared offices, open spaces, canteens, but also in the gathering areas of smart cities or simply for environmental impact measurement in urban construction sites, near schools or hospitals, or in retirement homes.
IoT Data Management Platform :
This device is combined with our cloud-based data supervision solutionTelemesure.net. Users can view and manage all their measurement data remotely, and receive real-time alerts or notifications via a browser or cell phone.
