This document summarizes a student project on a GSM-based fault monitoring system for cell phone towers. The system uses a GSM modem and microcontroller to detect faults and send SMS alerts to supervisors. It allows remote monitoring of power grids and industries without needing on-site staff. The project aims to design an indication system for overvoltage and over-current faults. Key components are a GSM modem to connect to the mobile network and an 89S51 microcontroller. The system provides long-life, low-cost monitoring without maintenance through SMS alerts. It has applications for power grids, factories, and home automation.
