Wireless Health And Security Monitor That Does Not Breach Privacy

This privacy-preserving health and security monitor functions by combining an ESP microcontroller with a millimeter-wave (mmWave) radar sensor and a display screen, all programmed using the Arduino IDE. The mmWave radar sensor acts as the core data-gathering component, emitting high-frequency radio waves that bounce off objects, walls, and human bodies within its range. Because it relies on radio frequency reflections rather than optical light, it can detect micro-motions caused by respiration as well as macro-motions like walking or sleeping without capturing any identifiable visual imagery. The ESP board processes the raw radar signals via a dedicated radar interfacing library, extracting actionable metrics regarding an individual's presence, movement state, and vital signs. Once the ESP board computes this telemetry data, it outputs the results visually onto the attached display screen in real time. Additionally, the built-in wireless capabilities of the ESP board allow it to transmit these processed health and security metrics over a local network, enabling remote observation without sacrificing individual privacy.
