ToF & PIR Bathroom Occupancy Sensor (VS330)
An advanced indoor presence and occupancy sensor combining short-range Passive Infrared (PIR) motion triggers with millimetric Time-of-Flight (ToF) distance sensing. Featuring a multi-position adjustable sensor orientation layout, comprehensive local power controls, and a tool-free NFC configuration interface, it provides a precise, privacy-safe solution for facility cubic space management in a flame-retardant white enclosure.
Key Highlights
- Advanced ToF Detection Technology: Leverages Time-of-Flight sensing for high-accuracy distance tracking measurements.
- Integrated Dual Sensor Technology: Combines ToF capability with passive infrared technology to optimize presence checks.
- Adjustable Mechanical Sensor Angle: Features flexible rotation locks at multiple specific preset degree increments.
- Decade Horizon Battery Engineering: Optimized architecture yields multi-year operations under specified user thresholds.
- Frictionless Contactless NFC Customization: Implements quick configuration loops for setup changes via smartphone app.
Product Overview
The hardware functions as an advanced indoor ToF and PIR presence sensor explicitly engineered to deliver high-resolution millimeter-level distance tracking and thermal occupancy oversight across enclosed facilities and restroom cubicles. It aggregates a sophisticated dual-sensor matrix merging a narrow 27° Time-of-Flight (ToF) transceiver covering a detection range of 0.040 to 3.500m with an accuracy threshold of ±2cm and an 80° Passive Infrared (PIR) element tracking initial movement parameters up to a maximum distance of 2.5m. To simplify target recalibration post-installation, the physical sensing core incorporates an adjustable orientation mechanism that locks securely across multiple precise angle presets including 0°, 15°, 30°, 45°, 60°, and 75°.
Operating over standard universal long-range networks as a low-power OTAA/ABP Class A node, the device features comprehensive physical interfaces containing an internal status/test LED indicator alongside a power/reset button. The system provides excellent operational sustainability, drawing power from three replaceable 4000 mAh ER18505 lithium-thionyl chloride batteries to yield a continuous service life scaling up to 4.2 years under intensive tracking configurations of 90 users within 7 consecutive hours per day. Encased in a compact white flame-retardant PC+ABS enclosure measuring exactly Ф100 x 24 mm, the wire-free module handles simple ceiling or wall-surface mounting via screws or 3M adhesive tapes while utilizing integrated near-field communication loops for tool-free, contactless diagnostic app configurations.
