Description

The Milesight WS302 is an advanced LoRaWAN Sound Level Sensor engineered for precise noise pollution monitoring in smart buildings and urban infrastructure. Equipped with a high-sensitivity integrated microphone, it captures a wide range of noise levels (30 dBA to 130 dBA) and transmits data via LoRaWAN for centralized analysis. Whether used for regulatory compliance, health monitoring, or acoustic optimization, the WS302 provides the critical data needed to manage environmental sound impact effectively.

Advanced Acoustic Intelligence

Multi-Weighting Support Features selectable frequency weighting (A/C) and time weighting (Fast) to align with global noise measurement standards for different scenarios.
Threshold Alarming Equipped with a built-in LED indicator and configurable threshold alerts to provide immediate visual feedback and network notifications when noise levels exceed limits.
