The Milesight WS201 is a compact LoRaWAN® smart fill level monitoring sensor built for modern smart restroom operations. Designed for small containers such as toilet paper or tissue dispensers, it helps facility teams reduce manual checks and respond faster with data-driven refill planning.
Key features:
- Accurate, non-contact ToF (Time of Flight) distance measurement with a 1–55 cm detection range and approximately ±1 cm accuracy, then converts readings into an easy-to-understand remaining percentage.
- Configurable threshold alarms and automated reporting, enabling proactive maintenance when supplies run low—especially effective when paired with a Milesight LoRaWAN® gateway and Milesight IoT Cloud for centralized dashboards, alerts, and reporting.
- Deployment-friendly hardware: an ultra-slim body (about 12 mm) that fits inside dispensers, 3M tape mounting, and NFC-based setup via mobile app for fast on-site commissioning. An internal damp-proof coating supports stable operation in humid restroom environments.
Use case: In malls, hotels, airports, and office buildings, the WS201 can be rolled out across multiple restrooms to monitor dispenser status remotely and streamline housekeeping routes. linko (Hong Kong) can advise on LoRaWAN® design, professional installation, and platform integration as part of a complete smart building solution.
