Milesight VS340 / VS341

VS34x is an occupancy sensor designed to detect whether desks or seats in a workspace are occupied, allowing for better management and optimization of space usage.
The standard version of the sensor VS340 uses PIR technology for detection.
The pro version VS341 applies additional Thermopile IR technology to provide more accurate and precise detection capabilities.
VS34x features an adjustable field of view angle for greater flexibility in different scenarios. With wireless detection and easy configuration, the VS34x offers reliable and convenient desk or seat arrangement optimization.
It is compatible with Milesight LoRaWAN® gateway and IoT Cloud solution, enabling real-time monitoring of desks and seats' status for effective remote management.
