Innovative Wi-Fi Location Tracking
A remarkable project demonstrates how an array of ESP32 devices can track Wi-Fi signals in three-dimensional space with impressive accuracy. By synchronizing the clocks of these devices, the system measures the time difference between Wi-Fi signals received at different points, allowing it to pinpoint the location of the signal source. This technology not only detects the position but also visualizes reflections off various surfaces, showcasing exceptional detail, down to centimeters in accuracy. Such advancements highlight the potential for low-cost, high-tech solutions using everyday hardware, raising interest in making the project open-source for wider accessibility.
