MacRay LToF LoRaWAN® Time-of-Flight Sensor
Product Overview
MacRay LToF is an industrial-grade LoRaWAN® Time-of-Flight (ToF) sensor engineered for high-accuracy occupancy monitoring, people counting, indoor analytics, distance measurement, and wireless laser sensing applications. Built using advanced infrared laser-based Time-of-Flight technology, the device delivers precise real-time spatial awareness and movement analytics for smart buildings, offices, warehouses, retail infrastructure, factories, hospitals, and Industrial IoT environments.
Designed specifically for privacy-safe indoor monitoring, the MacRay LToF LoRaWAN® ToF sensor performs accurate people counting, zone occupancy detection, movement tracking, and presence analytics without using cameras or capturing personal identity data. The sensor utilizes intelligent 3D depth mapping and laser distance measurement technology to detect motion patterns, room occupancy, entry/exit movement, and activity zones with millimeter-level precision.
The device supports LoRaWAN® v1.0.4 Class A communication, AES-128 encrypted wireless transmission, BLE-based configuration through the Macnman Maya App, and intelligent event-driven analytics for occupancy thresholds, restricted zone alerts, smart automation triggers, and facility utilization monitoring. Engineered with a power-operated architecture and industrial backup battery support, the MacRay LToF ensures uninterrupted monitoring even during intermittent power failures.
Whether deployed for smart office occupancy analytics, energy-efficient building automation, warehouse movement monitoring, retail footfall analysis, industrial safety monitoring, smart classroom utilization, or facility management intelligence, the MacRay LToF wireless Time-of-Flight sensor transforms physical movement into actionable real-time operational insights for connected smart infrastructure.
The MacRay LToF industrial LoRaWAN® laser sensor is fully compatible with major LoRaWAN® gateways and network servers including ChirpStack, The Things Stack, MQTT platforms, Orbiwise, and private industrial LoRaWAN® infrastructures — enabling seamless integration into SCADA systems, Industrial IoT dashboards, occupancy analytics platforms, and smart building ecosystems.
