Milesight WS202 PIR & Light Sensor
Featuring LoRaWAN®
WS202
Milesight WS202 is a LoRaWAN® PIR sensor based on passive infrared technology to detect motion or occupancy. The WS202 can detect movement within a range of 6-8 meters and send the changes via a LoRaWAN® network. Additionally, the WS202 is equipped with a light sensor that can link PIR detection results to trigger scenes. With its compact size and battery power, the WS202 is easy to install anywhere. Compliant with the Milesight Development Platform, users can monitor room alarms or occupancy and trigger other sensors or appliances remotely.
The WS202 can be widely used in smart homes, smart offices, schools, and warehouses.
