Description

The Milesight WS203 is a versatile 3-in-1 LoRaWAN Motion & Environmental Sensor designed to maximize building efficiency and occupant comfort. By combining Passive Infrared (PIR) technology with precise temperature and humidity probes, it provides a comprehensive view of room utilization and climate status. The device is uniquely flexible, coming with multiple PIR covers to adjust detection angles for specific layouts. Supporting the Milesight D2D protocol, the WS203 can trigger lighting or HVAC units in under a second, functioning as a standalone controller that operates independently of the network backhaul.

Smart Occupancy & Climate Control

Milesight D2D Connectivity Utilize the WS203 as a D2D controller to instantly activate lights or fans upon motion detection, ensuring zero-latency response for occupants.
High Data Integrity Internal storage for 1,000 records and data retransmission features safeguard your analytics against network interruptions.

Professional Smart Building Scenarios

• Workplace Management: Monitor desk occupancy and room usage to optimize office real estate and cleaning schedules.
• Automated Lighting: Reduce energy costs by ensuring lighting is only active in occupied areas through D2D triggers.
• Health & Safety: Maintain ideal indoor air conditions in hospitals and schools with constant temperature/humidity tracking.
