WS202 PIR & Light Sensor

WS202 AI Workplace LoRaWAN PIR & Light Sensor

• PIR Presence Detection
• Brightness Measurement
• LoRaWAN® Wireless
• Easy Configuration (via NFC)

Precise Human Presence Detection

Combining advanced PIR motion detection technology with brightness measurement capabilities, the Milesight WS202 accurately determines whether an indoor space is occupied by detecting human activity and environmental light conditions.

Enable Automated & Intelligent Lighting Management

Through integration with Milesight Smart Switch or other LoRaWAN® lighting control devices, the WS202 enables automatic light activation when people enter a space and deactivation when they leave, creating efficient energy management systems.

Extensive Detection Coverage

• 120° Horizontal Detection
• 100° Vertical Detection
• Up to 8 m Detection Distance

Advanced Brightness Monitoring

• 1 lux resolution precision
• Measurement range from 1 to 60,000 lux
• Customizable threshold-based Bright/Dark determination

Simple Configuration Process

Device activation and configuration is streamlined through NFC technology, enabling setup via mobile phone or PC for quick deployment.
