ATL by the looks.
Great addition for any smart home. Many potential automations can be setup with this, such as turning lights on/off based on detection.
It has a pet mode and adjustable sensing distance.
From Amazon:
- Matter Multi-platform Compatibility: Use any Matter-supported hub (e.g., Amazon Echo, Google Nest) to control this presence sensor. Matter dose not require a cloud account and data is more secure
- Radar+PIR+Light 3-in-1 Sensor: Combines PIR and millimeter wave radar to detect both motion and human presence (even without any motion) with fewer false alarms compared to single-technology sensors. Enhanced by a built-in light sensor.
- Smart Home Integration: Keeps light on while reading, adjust the air conditioner, start the fan or control the lighting fixtures - all of which can be coordinated with a simple and sophisticated presence detector at the center.
- Wide Coverage & Easy Setup: The motion detector offers a wide detection range of up to 12 meters (with presence detection effective up to 6 meters). The 180° pivoting, 360° rotating base, and cable management allow flexible and neat positioning
- Pet-Proof Triggering & Privacy: Equipped with a removable pet-proof shield that prevents false alarms from pets or robotic vacuum. meross Matter Smart Sensor also features a camera-less design that eliminates the need for image capture or room mapping, prioritizing user privacy.
- Wired for Power: The smart PIR motion sensor requires continuous power for operation and the length of power cord is 1.5m. Adapter inside the package box
Similar Sensors from Aliexpress is around $5. XiaoMi's one is the longest lasting, I only changed battery once in past 10 years and still makding DingDong each time somebody walked in.
