    LoRaWAN® Sound Level Sensor

    WS302

    • Accurate Sound Level Measurement
    • LED Alarm Indicator
    • 1.5~4 Years Battery Life
    • Easy Configuration (via NFC)

    Fight Against Uncomfortable Noise


    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
    • A-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.

    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.

    Dainty as Always

    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

    Milesight Sound Level Sensor is compatible with industry-standard LoRaWAN® gateways with a range of up to 15 km in rural areas and 2 km in urban areas.

    Milesight IoT Cloud

    Compatible with Milesight IoT Cloud and view sound level at your fingertips.

    Long Battery Life

    Easy Configuration

    1st Step
    Install the Milesight ToolBox

    2nd Step
