Aqara has launched its first battery-powered presence sensor, the FP300, which can operate for up to three years on two CR2450 batteries, using PIR and radar sensors to detect movement and support various smart home automations across multiple platforms, though it lacks some advanced features of higher-end models.
Aqara's Presence Sensor FP2, utilizing millimeter wave radar technology, is receiving new features including Sleep Monitoring Mode, AI Person Detection, and People Counting. The sleep monitoring function analyzes sleep status, heart rate, and respiratory data, while AI Person Detection distinguishes between human and non-human motion. People Counting alerts users when people enter a room and provides the number of individuals present. The FP2's ability to detect specific movements allows for advanced automations. However, accuracy issues have been reported with the device. The sleep monitoring feature offers an affordable and non-intrusive option for tracking heart rate and breathing while sleeping. The FP2 is compatible with various smart home platforms and will support Matter in the future.
A presence sensor based on a 24 GHz radar module and an ESP32 microcontroller has been developed to automatically lock a computer screen when the user walks away from the machine. The sensor detects motion and sends the screen lock keyboard shortcut to the computer, ensuring security in offices with high foot traffic. The project can be implemented using various microcontroller platforms, and the addition of a blinking LED would provide a visual indication before the screen locks.
