What is Low Voltage Protection Device Design about?

This document summarizes a research paper that presents the design and construction of a low-cost microcontroller-based device for under and over voltage protection. The device uses a PIC16F877 microcontroller to monitor the voltage and control a relay that connects or disconnects the load. When the voltage is below or above the preset range of 200-240V, the microcontroller activates the relay driver transistor which switches the relay off, disconnecting the load. The device is designed to protect loads up
