Sound Sensor Featuring LoRaWAN

Loud noise can create physical and psychological stress, diminish productivity, and disturb concentration. What’s more, noise is one of the most frequent complaints.

Milesight WS302 LoRaWAN® Sound Level Sensor is a half-palm-size noise monitoring device with a minimalistic and modern design. By installing WS302 in each facility, administrators will receive an immediate alert and LED of WS302 will flash when a customized noise threshold is triggered, enabling admins to proactively handle noise issues before it results in noise complaints.

Important Information

Please note: For wireless network capabilities, an applicable Gateway is required to utilise the IoT Cloud software as demonstrated below.

  • OVERVIEW

    Fight against uncomfortable noise

    Milesight WS302 is a LoRa sound level sensor with integrated microphone. The WS302 can measure a wide range of noise levels and send various kinds of noise level values via LoRaWAN® Network. It can also support multiple weighting measurements for different application scenarios. Compliant with Milesight LoRaWAN® gateway and Milesight IoT Cloud solution, users can manage all sensor data and trigger other sensors or appliances easily via webpage or mobile App remotely. WS302 can be widely used in smart buildings, smart cities, schools, heath monitoring, etc.

    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.

    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.

     

    Features

    • Support multiple weighting measurements to suit different scenarios: A weighting, C weighting, fast weighting
    • Support measuring various kinds of values to judge the sound level accurately: actual value, equivalent continuous value and max value
    • Equipped with an LED indicator to indicate threshold alarms
    • More than 4 years battery life
    • Built-in NFC for easy configuration
    • Compliant with standard LoRaWAN® gateways and network servers
    • Quick and easy management with Milesight IoT Cloud solution

    Easy Configuration

    Switching on/off and configuring the device via NFC technology from mobile phone or PC

     

    Please note: For wireless network capabilities, an applicable Gateway is required to utilise the IoT Cloud software as demonstrated below.
