Smart Restroom Supply Management via LoRaWAN: Industrial IoT Solution with Milesight WS201 Level Sensor

Intro

Maintaining customer satisfaction in modern commercial facilities—airports, shopping malls, and public buildings—depends on clean, well-stocked restroom facilities. While toilet paper management may seem straightforward, large-scale facilities relying on manual checks and scheduled maintenance face inefficiency, high costs, and unreliable outcomes. Industrial IoT (IIoT) solutions now offer practical alternatives to these traditional challenges.

Challenge

Toilet paper supply management presents several critical obstacles:

Sensor Size and Space Constraints Compact sensors suitable for placement inside toilet paper dispensers are limited. Standard sensors occupy excessive space and complicate installation.

Power Supply Limitations Restroom stalls lack electrical outlets, making wired solutions impractical. Battery life must be extended, and replacement must be simple.

Secure Installation Metal partitions and humid environments complicate adhesive mounting. Sensors must remain firmly attached and resist accidental dislodgement.

Wireless Signal Instability Metal toilet paper dispensers and metal partitions attenuate LoRaWAN and other wireless signals, increasing the risk of communication loss.

Solution

The Milesight WS201 smart level sensor addresses these challenges through purpose-built design. Employing Time of Flight (ToF) technology, the WS201 measures toilet paper levels in real time and sends automatic alerts to maintenance staff. When stock drops below a preset threshold, the system immediately notifies cleaning personnel, ensuring customers never encounter empty dispensers.

Key WS201 Features:

• ToF Technology: Measures sensor-to-target distance with millimeter precision
• Ultra-Compact Design: 12mm thickness fits easily inside various dispenser sizes
• 3M Adhesive Mount: Secure attachment to metal and plastic surfaces
• LoRaWAN Connectivity: Long-range, low-power wireless communication
• Sleep Mode: Automatic energy conservation during closed hours (e.g., 22:00–09:00)
• Flexible Alerts: Percentage-based threshold configuration; no complex calculations
• Moisture Protection: Reliable operation in high-humidity restroom environments

Topologies

WS201 sensors connect to a centralized IoT platform via LoRaWAN infrastructure. Each sensor transmits level data at regular intervals. Milesight IoT Cloud and similar management platforms aggregate this data to:

• Provide real-time dashboard visibility
• Define automated alert rules
• Send notifications to maintenance staff via SMS, email, or mobile app
• Analyze historical data to optimize maintenance scheduling

Benefits

Operational Efficiency Maintenance staff respond only to system-generated alerts rather than conducting manual inspections of every restroom. This significantly reduces labor costs.

Customer Satisfaction Empty toilet paper dispensers are a leading source of customer complaints. Proactive monitoring eliminates this issue entirely.

Cost Savings Extended battery life (months), simple installation, and minimal maintenance. Sleep mode reduces battery replacement frequency.

Scalability Manage hundreds or thousands of sensors across a single LoRaWAN network. Ideal for airports, shopping centers, and hospitals.

Data-Driven Management Historical consumption data improves inventory planning and budget forecasting.

Next Step in Turkey

In Turkey's major facilities—airports, shopping malls, hospitals, and universities—toilet paper management represents a significant operational expense. LoRaWAN-based smart sensor solutions can reduce these costs by 30–40%. IoTMarketi offers project-based quotations for Milesight WS201 and comparable IIoT sensors.
