ESPectre uses Wi-Fi signals for camera-free motion detection

A new motion detection system called ESPectre utilizes Wi-Fi signal analysis to identify movement without cameras or microphones. The system, which integrates with Home Assistant, features an experimental machine learning-based detector that requires no calibration and runs on-device. ESPectre uses an ESP32 device to interpret disturbances in Wi-Fi waves caused by movement, offering applications in home security, elderly care, and smart automation. AI
