PIR Motion & Light Sensor (WS202)
A compact, intelligent indoor wireless occupancy sensor combining advanced passive infrared (PIR) thermal detection with real-time ambient light monitoring. Encased in a discrete white enclosure with tool-free NFC configuration and low-latency gateway-free automation layers, it provides a seamless solution for smart building climate controls and occupancy auditing.
Key Highlights
- Occupancy and Light Sensing: Combines a passive infrared motion trigger with a real-time illuminance monitor.
- Detection Range and Matrix: Provides dependable coverage up to 8 meters with an 110-degree horizontal radius.
- Integrated Peer Automation Controls: Pairs over custom Device-to-Device (D2D) loops for swift gateway-free hardware linkages.
- Multi-Year Standalone Power Footprint: Runs up to 5 years on a standard high-capacity lithium battery cell.
- Compact Non-Invasive Surface Form: Minimal physical profile allows discrete mounting matching room interior aesthetics.
Product Overview
The hardware functions as a compact, wire-free indoor PIR motion and light sensor explicitly engineered to deliver real-time occupancy auditing and ambient brightness tracking across modern commercial spaces, office facilities, and smart homes. It integrates a highly responsive passive infrared sensor field capable of mapping occupancy presence up to 8 meters away within a horizontal wide-angle window of 110°, working alongside an environmental illuminance detector to categorize regional lighting status as bright or dark. Outfitted with an integrated device-to-device wireless protocol layer
The node communicates local occupancy conditions directly with remote smart switches or electrical relays within milliseconds, enabling automated gateway-free fallback loops. The system delivers exceptional off-grid operational independence, drawing minimal power from a single replaceable 1200 mAh ER14250 lithium battery to achieve a reliable service life of up to 5 years. Encased in an elegant, discrete IP30-rated white polycarbonate and ABS enclosure measuring exactly 50 × 50 × 23.8 mm, the sensor provides versatile installation options using simple wall screws or non-invasive double-sided 3M adhesive tape, leveraging built-in near-field communication loops for rapid, tool-free diagnostic app pairing.
