The Milesight WS203 is an environmental monitoring device that combines motion and temperature/humidity (TH) sensors. By detecting motion within an 8-meter range using passive infrared (PIR) technology, the WS203 can trigger TH detection and periodically report environmental status over the LoRaWAN® network.
With easy configuration and wireless detection, the WS203 offers a reliable and convenient solution for space and TH optimisation. Compatible with a Milesight LoRaWAN® gateway, it enables real-time monitoring of occupant status for effective remote management. The WS203 can find applications in various settings including smart offices, buildings, hospitals, and more.
