Abstract
A tracking system is configured for personal safety and security. The tracking system includes an Internet of Things (IoT) device having a multifunctional ultraviolet (UV) light sensor and optionally includes one or more Time of Flight (ToF) sensors. The multifunctional UV sensor is used to detect when smoke particles exceed a threshold and when UV light exceeds a threshold. The thresholds vary depending on the location of the IoT device. The system can present an alert to a user when the thresholds are exceeded. The ToF sensor(s) can be used to build a baseline three-dimensional (3D) visualization of a secured zone, and alert the user of the presence of an unexpected person in that zone based on the 3D visualization.
