Sound Level Sensor

Description

Combat disruptive noise

The Milesight WS302, equipped with an inbuilt microphone, is a LoRaWAN® sound level sensor designed to tackle unwanted noise efficiently. This sensor is adept at capturing a vast array of noise intensities, transmitting detailed noise data through the LoRaWAN® Network. It offers flexible weighting options for a variety of use cases. Compatible with both the Milesight LoRaWAN® gateway and the IoT Cloud platform, it enables users to effortlessly control sensor data and automate responses across devices from anywhere, via a web interface or mobile application. The WS302 finds extensive application in intelligent urban development, educational institutions, health monitoring systems, and more.

Effortless Sound Monitoring

The WS302 stands out as a sophisticated noise/sound level sensor within the LoRaWAN® ecosystem, simplifying the monitoring of decibels (dB).

• Noise Measurement Range: 30 to 120 dBA
• Precision: ±3 dB; Resolution: 0.1 dB
• Options for A-Weighting, C-Weighting, and Fast-Time Weighting
• Reporting Metrics: SPL Actual, Leq, and Lmax

Selecting Weightings Based on Environment

Opt for A-weighting in quieter settings and C-weighting in louder environments, enhancing the sensor’s versatility.

Rapid Response to Noise Fluctuations

With a 125-millisecond time constant, fast-time weighting excels in tracking rapidly changing noise levels, although activating this feature may impact battery longevity.

Comprehensive Noise Analysis

The sensor reports on three critical sound metrics—maximum sound level, sound pressure level, and equivalent continuous sound level—tailored by different weighting methods.

Seamlessly Integrates into Any Setting

With its sleek design, the WS302 is perfectly suited for educational spaces, professional settings, healthcare facilities, and more, serving as an unobtrusive sentinel against noise pollution.
