Design and Implementation of an IoT-Based Wireless Health and Voltage/Current Control System

The “Wireless Health and V/I Controller” project proposes a compact embedded system that combines wireless monitoring of selected health parameters with voltage and current measurement and control for low-voltage electrical loads. A microcontroller collects readings from suitable sensors, processes the data, compares values with predefined limits, and sends readings and status information to a mobile or computer interface through wireless communication. The health section can monitor body temperature, heart rate and SpO₂ when appropriate sensors are used. The electrical section measures voltage and current and can control a connected load according to programmed conditions. Alerts can be generated when readings cross preset thresholds. The design is intended as a low-cost educational prototype and is not a replacement for professional medical diagnosis or certified medical equipment.
