Milesight WS302 LoRaWAN Sound Level Sensor

Description

 

Milesight WS302 LoRaWAN Sound Level Sensor

WS302 is an advanced LoRaWAN® Sensor for monitoring noise/sound level in decibels (dB) with ease.

  • 30 to 120 dBA Measurement Range
  • ± 3 dB Accuracy; 0.1 dB Resolution
  • A-Weighting, C-Weighting & Fast-Time Weighting
  • Measurement Unit: SPL Actual, Leq, and Lmax
  • Accurate Sound Level Measurement
  • LED Alarm Indicator
  • 1.5~4 Years Battery Life
  • Easy Configuration (Via NFC)

A & C Weighting as Needed

Choose A-weighting or C-weighting based on scenarios. Usually, A-weighting is appropriate for quiet environments while C-weighting is for noisy environments.


Fast-Time Weighting

Fast-time weighting uses a time constant of 125 milliseconds for measuring unstable noise with large fluctuations.

Fast weighting is turned off by default. When turned on, battery life will be shortened.


More Sound Levels for more Insight

Support reporting of three sound level values (maximum sound level, sound pressure level, and equivalent continuous sound level) based on different weighting methods.
