Fill level sensor Milesight WS201-868M — LoRaWAN IoT smart fill level

The Milesight WS201-868M is a LoRaWAN-enabled IoT sensor for continuous fill level monitoring of tanks, bins and containers. It measures distance to the surface of liquids or bulk materials and sends level or distance data via LoRaWAN for integration with remote monitoring, asset management and alerting platforms. The device is designed for low-power operation and long-range wireless telemetry, making it suitable for distributed installations where battery life and network coverage are important.

Advantages

The sensor offers reliable remote level measurement with LoRaWAN connectivity, enabling long-range transmission and low energy consumption for extended battery life. It supports continuous distance or calculated fill-level reporting, allowing straightforward integration into existing IoT platforms and alarm systems. The compact form factor and robust design suit outdoor and industrial environments while minimizing installation complexity.

Suitable for

• Waste container and skip level monitoring
• Water tank and reservoir level measurement
• Fuel storage and dispensing tank monitoring
• Bulk material and hopper fill-level tracking

Key specifications

• Wireless protocol: LoRaWAN (868 MHz band)
• Measurement type: distance-to-surface for level calculation
• Power: low-power design for extended battery operation
• Deployment: suitable for outdoor and industrial installations
• Reporting: periodic and event-based data transmission over LoRaWAN

How to use

Mount the WS201-868M sensor above the measured surface following the manufacturer’s mounting guidelines to ensure a clear line of sight to the target area. Configure LoRaWAN network settings and device parameters using the supported provisioning method, then pair the device with your LoRaWAN network server or cloud platform. Define reporting intervals, thresholds and alarm rules in the receiving system to convert distance readings into actionable fill-level data and alerts.

Recommendations

For accurate measurements, position the sensor so the beam faces the material surface without obstructions and away from turbulence or heavy foam. Choose reporting intervals that balance timeliness and battery life, and validate integration with your asset management or alerting system during initial deployment.
