Aqara Motion and Light Sensor P2
Dual-function sensor with motion detection and ambient light sensing
The Aqara Motion and Light Sensor P2 is a compact dual‑function device combining PIR motion detection with a precision ambient light sensor to enable intelligent, energy‑efficient automations. It triggers scenes only when motion is detected and ambient light is below your chosen threshold — perfect for automatic lighting, security notifications, and context‑aware smart home control.
Intelligent Motion & Ambient Light Sensing for Smarter Automations
This sensor uses passive infrared (PIR) technology to detect human movement up to 7 meters and a built‑in light sensor to measure ambient illumination from 0 to 1000 lux. By combining both inputs, it avoids unnecessary triggers (for example during daylight) and ensures automations like lights or HVAC run only when needed — saving energy and reducing false activations.
How It Works
When motion is detected within the device’s 170° field of view, it checks the ambient light level. If the light level is below a configured threshold, the sensor sends a Zigbee event to your hub to run scenes such as turning on lights, starting camera recording, or sending a mobile alert. The detection interval is adjustable (10s to 30min) to balance responsiveness and battery life.
Key Benefits
- Dual detection reduces false triggers by combining motion and light conditions.
- Energy savings — lights and devices run only when movement and low light are both detected.
- Long battery life (CR2450) — up to 2 years under normal use.
- Wide coverage — up to 7 meters and 170° detection angle for reliable room coverage.
- Easy installation — wall mount or magnetic base for flexible placement.
- Integrates with Zigbee 3.0 hubs for automations with lights, locks, cameras, and more.

Use Cases & Automation Ideas
- Hallway lights that only turn on at night when motion is detected.
- Porch or stair lighting that ignores daytime movement.
- Security integrations — trigger cameras or send alerts when movement occurs in low light.
- Energy management — avoid HVAC or lighting runs when rooms are unoccupied or already bright.
