Fill Level Monitoring Sensor ToF LoRaWAN EU868 – Milesight WS201

The Milesight WS201 is an ultra-compact, battery-powered fill level monitoring sensor designed for accurate level detection in small spaces. It uses ToF (Time-of-Flight) distance measurement across a 1–55 cm range and features a minimal blind zone of just 1 cm, making it well suited for tight dispenser and container installations.

Instead of routine inspections, teams can rely on threshold-based alerts to trigger refills exactly when needed. This improves service quality, avoids stockouts, and reduces operating effort—especially when many distributed points must be maintained.

Typical applications include:

Monitoring paper and towel dispensers in public facilities

Refill management in offices, hotels, restaurants, and malls

Shelf stock level monitoring for consumables or spare parts

Any small container where quick, reliable “low level” alerts matter

Alerts can be configured using custom threshold levels to match operational processes. WS201 also supports Hibernate Mode to align reporting with opening hours and reduce unnecessary transmissions.

Configuration is done via NFC using a mobile app or via downlink. For fast deployment, it mounts on flat surfaces using 3M tape, keeping maintenance simple and minimizing installation overhead.
