Milesight's full smart facility management sensor suite covers every aspect of restroom and building operations — soap, toilet paper, leaks, odor, occupancy, waste bins, flush monitoring, and cleaning optimisation. All connect via LoRaWAN to Vemcount IoT dashboards. Gateway: Milesight UG65/UG67/SG50 → ttn.vemcount.app UDP 1700.
Traditional facility management runs on fixed cleaning schedules — staff visit whether needed or not, run out of supplies between visits, miss leaks for hours, and can't prove hygiene SLAs. IoT sensors flip this to condition-based maintenance: clean when needed, restock before empty, alert on leaks immediately, generate auditable hygiene reports automatically.
The core restroom consumables sensor. ToF laser measures how full a toilet paper or soap dispenser is — outputs percentage directly, no distance calculation needed.
Technology | Time-of-Flight laser, 1cm blind zone minimum, high close-range accuracy |
Metal-compatible | Works inside metal toilet paper boxes — high LoRa signal penetration |
Form factor | Ultra-thin body, 3M adhesive mount, buckle-open lid for easy battery replacement |
Battery | Up to 2 years on one coin cell |
Configuration | NFC — set % alert threshold directly (e.g. alert at 20%), no distance calculation |
Sleep schedule | Auto-hibernate during closing hours — saves battery in malls and offices |
Environment | Damp-proof coating — stable in humid bathrooms |
Use cases: Toilet paper roll level per cubicle, liquid/foam soap dispensers, paper towel dispensers, hand sanitiser dispensers in lobbies.
Per-stall occupancy monitoring for individual toilet cubicles, accessible bathrooms, and fitting rooms. Combines ToF + PIR for >99.5% accuracy, 100% anonymous.
Technology | ToF (distance) + PIR (motion) — dual detection prevents false positives |
Accuracy | >99.5% detection — industry-leading for enclosed spaces |
Privacy | 100% anonymous, no image, GDPR compliant |
Rotatable probe | 0–75° adjustable — minimal blind spot, flexible mount angle |
Environment | PCBA conformal coating — reliable in humid conditions |
Use cases: Live stall availability display boards, usage counting per stall, cleaning trigger by usage count, accessible stall monitoring in airports and malls.
Cleaning optimisation workflow: VS330 usage count + WS201 consumable % + WS101 request button → Vemcount triggers cleaning alert when stall has been used N times since last clean, OR consumables drop below 20%, OR button pressed. Staff dispatched on demand — not on fixed schedule.
Gases | Ammonia (NH₃) + Hydrogen sulphide (H₂S) — electrochemical sensors for restroom malodor compounds |
Environmental | Temperature + Humidity |
Local alarm | LED traffic light + built-in buzzer when threshold exceeded |
D2D automation | Direct ventilation fan control without gateway — sub-second response to odor spike |
Detects e-cigarette/vaping aerosol. Sends immediate LoRaWAN alert. For restrooms, changing rooms, and school toilets where vaping is prohibited.
Detection | 0.5mm water threshold — catches leaks before flooding. Gold-plated probes, corrosion-resistant. |
Enclosure | IP67 fully waterproof |
Battery | Up to 5 years on 1× CR2450 |
Alert | Local buzzer + LoRaWAN uplink. Capacitor backup — sends alarm during power failure. |
Use cases | Under toilet cistern, under sink unit, floor drain overflow, behind urinals |
EM300-SLD: spot sensor for plant rooms, behind toilet banks. EM300-MLD: flexible membrane strip that lays along pipe runs or across large floor areas — detects moisture across the full membrane length.
Designed for small and mini bins — desk bins, individual office bins, small restroom waste bins. Almost zero blind spot. Bin Mode pre-configured. Detects: fill level + lid status (open/closed) + trash combustion (fire/smouldering). IP67. LoRaWAN or NB-IoT.
For wheelie bins, corridor litter bins, large restroom sanitary waste containers. 3–450cm range. Detects: fill level + bin lid status (3-axis accelerometer) + trash combustion (NTC thermistor) + tilt/knock detection. Battery life up to 10 years. IP67. LoRaWAN or NB-IoT (NB-IoT version adds GNSS tracking).
Three pre-set modes: Standard / Bin Mode / Parking Lot Mode.
Dual ultrasonic, 3–450cm, 3-axis accelerometer, IP67. End-of-life — Milesight recommends EM400-MUD for new deployments. Fully supported for existing installations.
Counts actual visitors entering/leaving the restroom. Every N visits (configurable) triggers a cleaning recommendation in Vemcount. No more fixed-schedule cleaning, no more missed high-traffic surges. See VS133 setup guide for installation details.
Battery-powered LoRaWAN button. Single press / double press / long press each trigger different events. No wiring — adhesive mount installs in minutes. Use cases: visitor-triggered cleaning request, staff cleaning complete confirmation (long press), emergency maintenance alert.
Consumables | WS201 per toilet paper dispenser + WS201 per soap dispenser |
Stall occupancy | VS330 per cubicle |
Entrance count | VS133 above entrance door |
Odor | GS301 (NH₃ + H₂S) — 1 per restroom area |
Leak detection | WS303 under each sink + EM300-SLD behind toilet bank |
Waste bins | EM400-TLD (small) or EM400-MUD (medium/large) |
Cleaning button | WS101 inside restroom |
Water consumption | EM300-DI on restroom water meter pulse output |
Vaping detection | GS601 if required |
Gateway | 1× UG65 covers full restroom block (200m radius) |
Consumables map — live % fill for every dispenser on a floor plan. Red when below threshold.
Usage-based cleaning triggers — alert after N visits. Log cleaning completion via WS101 button press.
Leak alerts — immediate notification to facility manager on any WS303/EM300 trigger.
Bin fill map — floor plan view showing which bins need emptying across the building.
Odor alerts — NH₃/H₂S threshold breach triggers immediate cleaning dispatch.
Hygiene reports — automated daily/weekly reports: cleaning events, consumable usage, sensor event history for SLA evidence and tenant reporting.
