The Story
Milesight Sound Level Sensor WS302-868M
Features:
- Accurate Sound Level Measurement
- LED Alarm Indicator
- 1.5~4 Years Battery Life
- Easy Configuration via NFC
Fight Against Uncomfortable Noise
WS302 is a LoRaWAN®-enabled sound level sensor that is designed to measure and monitor sound levels in various environments.
Monitor Sound Level
with Ease
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
-
Weighting, C-Weighting & Fast-Time Weighting
-
Measurement Unit: SPL Actual, Leq, and Lmax
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.
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.
Blend into any Interiors
Fight Against Uncomfortable Noise
Minimalistic and modern design makes it ideal for classrooms, workplaces, hotels, hospitals, etc. WS302 is an unnoticed guard for eliminating noise pollution.
LoRaWAN® Based
-
