VS321 is a low-power, battery-operated wireless occupancy sensor empowered by advanced AI algorithms. It achieves up to 95% occupancy detection accuracy powered by its AI algorithm. It is equipped with built-in temperature, humidity, and ambient light sensors to provide comprehensive environmental monitoring. Itswire-free design enables effortless and flexible installation. With simple configuration and wireless detection, VS321 can be integrated with the Milesight LoRaWAN®gateway and Milesight Development Platform, enabling remote monitoring, data visualisation, and centralised management. As a Milesight D2D controller, VS321 seamlessly communicates with other Milesight D2D devices, enabling peer-to-peer interaction without gateway dependency. VS321 can be used in scenarios such as meeting rooms, offices, and campuses to detect space occupancy or personnel activity.
