US915 LoRaWAN sound level sensor for indoor noise monitoring
The WS302 milesight Sound level sensor (dB) US Version measures and monitors sound levels in offices, classrooms, hospitals, hotels and other indoor environments. This version uses the US915 LoRaWAN frequency plan for compatible networks in the United States.
Sound data is transmitted through LoRaWAN to a compatible LoRaWAN gateway and monitoring platform for visualisation, alarms and historical analysis.
Sound measurement and configuration
The sensor measures from 30 to 120 dBA or 35 to 120 dBC with 0.1 dB resolution. It supports A and C frequency weighting and reports SPL Actual, Leq and Lmax values.
Configurable thresholds and the integrated LED can provide a local warning when the selected noise level is exceeded. Configuration is performed 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.
