LoRaWAN sound level sensor for indoor noise monitoring
The WS302 milesight Sound level sensor (dB) LoRaWAN measures and monitors sound levels in offices, classrooms, hospitals, hotels, libraries and other indoor environments.
Sound data is transmitted through LoRaWAN to a compatible LoRaWAN gateway and monitoring platform for visualisation, alarms and historical analysis.
Sound measurement and configurable alarms
The integrated microphone measures from 30 to 120 dBA or 35 to 120 dBC with a resolution of 0.1 dB. The sensor supports A-weighting, C-weighting and optional fast-time weighting.
WS302 reports actual sound pressure level, equivalent continuous sound level and maximum sound level. Configurable thresholds and the integrated LED indicator can provide a local warning when the selected noise limit is exceeded.
The device is configured through NFC using the Milesight ToolBox app or remotely through LoRaWAN downlink commands.
See the official Milesight WS302 product information and documentation for detailed specifications and configuration guidance.
