Milesight smart restroom sensors connect via LoRaWAN to Vemcount IoT dashboards. All sensors in this group are battery-powered, wireless, and designed for commercial bathroom environments — hotels, shopping malls, airports, office buildings. Gateway required: Milesight UG65/UG67 or SG50 pushing to ttn.vemcount.app UDP 1700.
VS373 — Radar Fall Detection Sensor
The most advanced sensor in the restroom range. Uses 4D 60GHz millimeter-wave radar (MIMO array: 24 TX + 22 RX) for contactless monitoring — no camera, 100% privacy compliant.
Technology | 4D mmWave 60GHz radar + AI algorithms |
Fall detection accuracy | Up to 99% capture rate, <1% false alarm rate |
Connectivity | LoRaWAN + WiFi |
Detection functions | Fall detection, motionless/overstay detection, bed presence monitoring (single and multi-bed), room occupancy, sub-region occupancy |
Alert system | 3-phase alert: Confirmation (red LED slow flash) → First Alert (red LED fast + buzzer) → Emergency (report sent) |
Privacy | 100% — no camera, no images, only radar point cloud data |
Mounting | Ceiling mount. USB-C powered. Side cable non-removable. |
D2D support | Yes — direct integration with other Milesight devices (alarms, door locks) without gateway |
Use cases | Nursing home rooms, hospital wards, accessible/smart public restrooms, hotel rooms, elderly care facilities |
Beyond fall detection the VS373 also supports sub-region independent occupancy, so a single sensor can monitor different zones of a room simultaneously.
VS330 — Bathroom Occupancy Sensor
Dedicated LoRaWAN occupancy sensor for restroom cubicle/stall monitoring. Detects whether a toilet stall is occupied or vacant. Enables real-time display boards showing which stalls are free, and tracks cleaning cycle triggers based on usage counts.
Technology | Infrared / radar occupancy sensing |
Connectivity | LoRaWAN |
Use cases | Toilet stall occupancy dashboards, cleaning trigger automation, restroom usage analytics |
GS301 — Bathroom Odor Detector (4-in-1)
Detects odor gases and environmental conditions simultaneously — ideal for triggering automatic ventilation in restrooms and monitoring hygiene levels.
Sensors | Ammonia (NH₃) + Hydrogen sulphide (H₂S) via electrochemical principle + Temperature + Humidity |
Alert | LED traffic light indicator + built-in buzzer + LoRaWAN uplink when NH₃ or H₂S exceeds threshold (customizable) |
D2D / HVAC control | Supports Milesight D2D for direct, ultra-low-latency HVAC control without a gateway — when NH₃/H₂S rises, the ventilation activates automatically |
Mounting | Wall mount. Damp-proof coating for bathroom environments. |
Use cases | Hotel/mall bathroom ventilation control, hygiene monitoring, odor alerting |
WS201 — Smart Fill Level Monitoring Sensor
Monitors how full toilet paper dispensers, soap dispensers, and paper towel holders are — triggering alerts when supplies run low so cleaning staff only visit when needed.
Technology | Time-of-Flight (ToF) distance measurement. Blind zone: 1cm minimum. |
Battery | Up to 2 years on one coin cell battery |
Mounting | Ultra-thin body, 3M adhesive. Works inside metal toilet paper boxes. Damp-proof coating. |
Configuration | NFC via Milesight ToolBox app. Set % thresholds (not distance calculation) |
Schedule hibernate | Auto-sleep during closing hours (e.g. 22:00–09:00) to save battery |
Use cases | Toilet paper level monitoring in malls/hotels/airports, soap dispenser fill alerts, paper towel dispensers |
WS301 — Magnetic Contact Switch (Door/Window)
Detects open/close state of bathroom stall doors, utility room doors, or cabinet access. Can be used as a low-cost stall occupancy indicator or for security access monitoring.
Battery life | Over 4 years |
Tamper detection | Yes — alerts if device is removed from mounting |
Compatibility | Various door/window materials and types |
Use cases | Stall door open/close monitoring, utility room access, restroom entrance counting trigger |
WS303 — Mini Leak Detection Sensor
Detects the presence of water or other conductive liquids on the floor — for early warning of pipe leaks, overflow, or flooding in wet environments.
Detection | Water conductivity — detects minimum 0.5mm water level via gold-plated probes. Also detects other conductive liquids. |
Battery | Up to 5 years on 1× CR2450 590mAh coin cell |
Enclosure | IP67 — waterproof and dustproof |
Alert | Built-in buzzer (local) + LoRaWAN uplink (remote). Capacitor storage for power-failure alarm. |
Mounting | Surface or wall mount — compact, wire-free |
Use cases | Under-sink leak detection, bathroom floor flooding, pipe burst monitoring, server room water intrusion |
GS601 — Vape Detector
Detects vaping/e-cigarette aerosol in enclosed spaces where smoking is prohibited — bathroom stalls, changing rooms, school toilets.
Detection | Vape/e-cigarette aerosol detection |
Connectivity | LoRaWAN |
Alerts | Local + LoRaWAN uplink alarm |
Use cases | School bathrooms, hotel rooms, shopping mall restrooms, change rooms — anywhere vaping is prohibited |
Connecting to Vemcount
All sensors connect via a Milesight LoRaWAN gateway (UG65, UG67, or SG50). The gateway pushes data to Vemcount at ttn.vemcount.app UDP port 1700. Sensor data appears in the Vemcount IoT dashboard as occupancy states, fill level percentages, gas concentrations, and event alerts. Configure threshold-based notifications in Vemcount for automated cleaning dispatch and maintenance alerts.
