KANKANAL Smart Fill Level Monitor
Ultra-compact, wireless ToF sensor that tracks consumable fill levels in real time, enabling predictive housekeeping and smarter facility operations.
Product Overview
The KANKANAL Smart Fill Level Monitor is a miniature, battery-powered sensor that uses Time-of-Flight (ToF) technology to measure how much tissue, towel or other consumable is left in a box or dispenser. Designed for smart restrooms, hospitality spaces and large workplaces, it sends wireless updates via LoRaWAN to KANKANAL DeviceBoard, allowing facility teams to see fill levels in real time, optimise cleaning routes and ensure that dispensers never run empty.
1. High-Precision Time-of-Flight Fill Detection
- Uses Time-of-Flight (ToF) technology for highly accurate distance measurement.
- High-focus detection range of approximately 1–55 cm, ideal for tissue boxes and small containers.
- Fine resolution across the full range, enabling centimetre-level fill estimation.
- Non-contact sensing avoids contamination and wear, making it perfect for hygiene-critical areas.
2. Fill Percentage & Smart Thresholds
- Automatically converts measured distance into a remaining fill percentage.
- Configurable thresholds (for example 20% remaining) to trigger refill alerts.
- Supports different container heights and shapes through simple configuration.
- Ideal for connecting to DeviceBoard workflows that create cleaning tasks or tickets when refill is needed.
3. Ultra-Low Power Operation
- Powered by a compact lithium battery designed for multi-year operation at typical reporting intervals.
- Intelligent sleep modes minimise energy use between readings.
- Configurable reporting frequency (for example every 15, 30 or 60 minutes) to balance responsiveness and battery life.
- Perfect for large-scale deployments where frequent battery changes would be costly.
4. Compact Design & Fast Installation
- Very small enclosure suitable for inside or under dispensers, boxes and cabinets.
- Lightweight device attaches using industrial-grade adhesive tape – no drilling or wiring.
- Ideal for retrofitting existing tissue and towel dispensers without redesign.
- Discreet, modern design that does not disturb restroom or lobby aesthetics.
5. Reliable in Humid Restroom Conditions
- Internal design includes damp-proof protection for high-humidity environments.
- Works reliably in washrooms, kitchens, hotel bathrooms and other indoor public spaces.
- Operating temperature and humidity ratings suited for air-conditioned as well as naturally ventilated buildings.
6. LoRaWAN Connectivity & DeviceBoard Integration
- Built-in LoRaWAN radio for long-range, low-power communication through KANKANAL LoRaWAN Gateways.
- Optimised payloads for small data packets, reducing airtime and extending battery life.
- Fully integrated with KANKANAL DeviceBoard for:
- Real-time fill level dashboards,
- Housekeeping and cleaning alerts,
- Analytics on consumable usage and replenishment cycles.
- Supports large multi-site deployments with centralised monitoring.
7. Simple Commissioning & Fleet Management
- Quick configuration using NFC-based mobile tools or network downlinks.
- Supports bulk provisioning of many devices for large facilities.
- Reports battery status and connectivity metrics for proactive maintenance.
- Easily grouped and tagged inside DeviceBoard by building, floor, zone or restroom.
8. Typical Use Cases
- Smart restrooms in malls, airports, IT parks and campuses – monitoring tissue, towels and other consumables.
- Hotels & hospitality – amenity refill monitoring in guest rooms and public areas.
- Corporate workplaces – washroom and pantry consumables across multiple floors.
- Cleaning contractors – SLA-based service with proof of refill and data-driven route planning.
- Retail & public spaces – maintaining hygiene standards while optimising staff schedules.
9. Key Advantages
- Prevents stockouts by alerting teams before dispensers run empty.
- Reduces manual checks and optimises cleaning routes.
- Scales easily to hundreds or thousands of dispensers across buildings and sites.
- Low total cost of ownership thanks to long battery life and zero wiring.
- Seamless integration with KANKANAL LoRaWAN Gateways and DeviceBoard analytics.
