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.

Professional Noise Monitoring Scenarios

• Smart Offices: Monitor noise levels in open-plan workspaces to ensure occupant comfort and maintain high productivity standards.

• Smart Schools: Track decibel levels in libraries and classrooms to foster an ideal learning environment and detect disruptions.

• Industrial Safety: Monitor workshop noise to ensure compliance with hearing protection regulations and employee health guidelines.

Measurement Technology
- Multi-Weighting Support: Capabilities include A-weighting (human hearing simulation), C-weighting (high-pressure noise), and Fast-weighting for dynamic environments.
- Comprehensive Data Points: Reports three critical values per interval: actual sound level, equivalent continuous sound level (Leq), and maximum sound level (Lmax).
- Visual Threshold Alarms: Integrated LED indicator can be configured to flash when pre-set decibel thresholds are exceeded.
- NFC Configuration: Effortless provisioning and parameter setting via smartphone, ideal for large-scale building rollouts.
- Industrial-Grade Accuracy: High-performance microphone ensures reliable data for noise pollution assessment and workplace safety audits.
Measurement Range
- Sound Level Range: 30 dBA to 120 dBA (A-weighting) / 35 dBC to 120 dBC (C-weighting).
- Frequency Range: 20 Hz to 8 kHz.
- Operating Humidity: 0% to 95% (non-condensing).
Measurement Accuracy
- Sound Accuracy: ±3 dB (at 1 kHz, 94 dB).
- Data Reliability: Supports downlink acknowledgments and local configuration to ensure data integrity across the LoRaWAN network.
- Transmission Range: Up to 15km line-of-sight and 2km in dense urban/office environments.
Measurement Resolution
- Sound Level Resolution: 0.1 dB.
- Reporting Interval: Fully configurable (Default: 10 minutes) via NFC or Downlink.
- Weighting Resolution: Selectable A or C weighting modes based on project requirements.
