Aqara P2 Infrared Sensor Wireless Ceiling Wall White

The Aqara P2 Infrared Sensor Wireless Ceiling Wall White is a compact indoor motion and light sensor designed for ceiling or wall mounting. It combines passive infrared (PIR) motion detection with an integrated ambient light sensor to support lighting control and presence detection in home automation setups. The sensor operates on a 2405–2480 MHz wireless frequency range, is lightweight and compact (approximately 33.1 mm width and depth, and 41.6 mm height), and is supplied as a single unit suitable for various indoor environments.

Advantages

The device provides combined motion and light sensing in a single compact enclosure, enabling automated responses based on occupancy and ambient illumination. Native compatibility with modern smart home ecosystems using Thread and Matter improves cross-platform integration and simplifies setup when used with a compatible Thread border router and Matter controller. Low-power operation on replaceable coin cell batteries supports long service intervals and flexible placement without the need for wiring.

Suitable for

• Automated lighting control in living rooms, hallways and bedrooms
• Presence detection for energy-saving scenarios in bathrooms and kitchens
• Integration into smart home scenes and security routines
• Placement on ceilings or walls to monitor specific indoor zones

Key specifications

• Sensing technologies: passive infrared (PIR) motion detection and ambient light sensor
• Wireless frequency range: 2405–2480 MHz
• Detection angle: wide field (typical PIR wide-angle detection)
• Detection range: up to several metres for typical indoor use (installation and environment dependent)
• Power: replaceable coin cell batteries (dual CR2450 configuration)
• Mounting: ceiling or wall, includes adjustable stands for directional placement
• Color: white
• Dimensions: approximately 33.1 mm (width) × 33.1 mm (depth) × 41.6 mm (height)

How to use

Mount the sensor on a ceiling or wall using the included adjustable stands and orient it toward the area to be monitored. Insert the specified coin cell batteries according to the polarity markings. Pair the sensor with a compatible Matter controller or a supported smart home hub using the device setup procedure in the controlling app. Configure motion detection sensitivity and light-based triggers in the app where supported, and place the sensor away from direct heat sources or moving objects that could cause false triggers.

Usage recommendations

For reliable detection, install the sensor at a height and angle that covers the intended area without obstructions. Use the integrated light sensor to create automations that respond to both presence and ambient illumination levels—this reduces unnecessary switching and saves energy. Replace batteries before low-battery alerts to ensure continuous operation, and test placement and sensitivity after installation to fine-tune performance for the specific room layout.
