1. A tracking system configured for personal safety and security, the tracking system comprising:
a portable Internet of Things (IoT) device configured to track a location of a user, the portable IoT device including:
a multifunctional ultraviolet light (UV) sensor configured to:
measure smoke particles in an environment of the IoT device; and
measure UV light in the environment of the IoT device;
one or more network interfaces configured to:
connect the IoT device to a telecommunications network that administers an IoT tracking service,
wherein the IoT device and handheld mobile device are subscribed to the IoT tracking service;
connect the IoT device over a short-range radio link to a handheld mobile device that is paired to the IoT device;
at least one hardware processor; and
at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
determine, based on measurements of the multifunctional UV sensor, whether a first measure of smoke particles obtained in the environment exceeds a first threshold and whether a second measure of UV light in the environment exceeds a second threshold,
wherein the first threshold and the second threshold vary depending on the location of the IoT device;
generate an indication of potential harm to the user when the first measure exceeds the first threshold or when the second measure exceeds the second threshold; and
cause the tracking system to present an alert based on the indication of potential harm to the user.
