Milesight VS341 | LoRaWAN Ceiling Occupancy Sensor

The Milesight VS341 is an advanced Ceiling-Mounted LoRaWAN Occupancy Sensor designed for intelligent space management in smart offices and commercial buildings. By combining Passive Infrared (PIR) motion detection with Thermopile temperature-grid sensing, the VS341 accurately identifies human presence even when occupants are completely stationary. This dual-technology approach eliminates the false "vacant" readings common in traditional PIR-only sensors. With its sleek, discreet design and 100% anonymous detection—capturing no images or personal data—it is the ideal choice for privacy-sensitive environments. Integrated Milesight D2D support allows the sensor to trigger local HVAC or lighting systems instantly, optimizing comfort and energy usage simultaneously.

Dual-Tech Room Intelligence
