3D Occupancy & Environmental Sensor (VS321)

The hardware functions as an advanced indoor people counting and occupancy detection sensor explicitly engineered to deliver continuous spatial presence auditing and multi-source microclimate tracking across commercial work environments and smart office layouts. It aggregates a sophisticated optical processing lens establishing a wide field of view across a 129° horizontal and 93° vertical angle at installation heights spanning from 2.4m to 4m, requiring a baseline illumination threshold of 50 Lux to ensure full counting efficiency. Working alongside the primary optical processors, the node embeds an expansive 115° passive infrared tracking matrix mapping an occupancy radius of 4 meters when situated at a 3m ceiling height under standard 15°C reference conditions.

Environmental telemetry is governed by high-performance MEMS digital CMOSens® operating principles that track ambient temperature gradients from -40 °C to 125 °C and relative humidity levels from 0 to 100% RH, working in tandem with a built-in photodiode circuit that registers localized space status as bright or dim. Running over universal low-power Class A long-range network topologies with native support for low-latency device-to-device automation loops, the device manages an internal non-volatile memory caching up to 2,045 historical log entries with automated retransmission and retrievability options to eliminate data loss during wireless dropouts. Housed within a discrete, compact IP30-rated white or black optional enclosure measuring exactly 100 × 100 × 26 mm, the wire-free module mounts cleanly via overhead ceiling screw anchors or adhesive tape fixtures, leveraging integrated Bluetooth configurations for rapid smartphone-app calibration and drawing power from four replaceable 2700 mAh ER14505 lithium-thionyl chloride batteries to yield an exceptional off-grid operational footprint extending up to 11.3 years.
