Description

The Milesight WS201 is an innovative LoRaWAN Smart Fill-Level Sensor specifically engineered for close-range sensing applications. Utilizing advanced Time-of-Flight (ToF) laser technology, it provides millimetric accuracy in monitoring the remaining contents of small containers, most notably tissue boxes in high-traffic facilities. Its ultra-compact form factor allows it to be mounted inside dispensers without interfering with daily use. By digitizing supply levels, the WS201 enables facilities managers to shift from scheduled refills to data-driven, "on-demand" janitorial services, significantly reducing labor costs and improving user satisfaction in smart restrooms and hospitality environments.

Laser-Precision Supply Management

Optimized ToF Accuracy Unlike infrared sensors, ToF technology measures the actual travel time of light, ensuring precise readings regardless of the color or material of the contents.
Intelligent Reporting Supports percentage-based remaining amount reporting and features configurable alarm thresholds to notify staff only when refills are actually needed.

Smart Facility Scenarios

• Smart Restrooms: Real-time fill-level tracking for tissue and paper towel dispensers in airports and malls.
• Hotel Hospitality: Monitor amenity stock levels in guest rooms to optimize housekeeping workflows.
• Inventory Control: Discreetly monitor small parts bins or stationary supplies in corporate office environments.
