Product Description

The Milesight WS302 Sound Level Sensor is an advanced LoRaWAN®-enabled device designed to monitor and measure sound levels in a variety of environments. This sensor is an ideal solution for creating peaceful surroundings in spaces such as classrooms, hospitals, hotels, libraries, and offices. By measuring sound levels, the WS302 helps in managing and reducing noise pollution, enhancing the comfort and productivity of these environments.

The WS302 is capable of measuring sound levels from 30 to 120 dBA with an accuracy of ±3 dB and a resolution of 0.1 dB. It offers both A-weighting and C-weighting options, allowing for appropriate sound measurement in different settings - A-weighting for quieter environments and C-weighting for noisier ones. Additionally, it features fast-time weighting with a time constant of 125 milliseconds, suitable for measuring unstable noise with large fluctuations.

This sensor stands out for its long battery life, offering over 4 years of service without needing a battery replacement. It also supports NFC for easy configuration and is compliant with standard LoRaWAN® gateways and network servers, ensuring high compatibility and easy integration into existing networks.
