IOT-BASED POWER OUTAGE DETECTION AND ALERT SYSTEM USING GSM

Abstract

Power outages can disrupt daily life, damage appliances, and lead to financial losses if not detected and addressed promptly. This project proposes an IoT-based power outage detection and alert system using Arduino and GSM technology to monitor electricity supply in real-time and notify users via SMS when a power failure occurs. The system consists of an Arduino microcontroller connected to a voltage sensor to detect the presence or absence of AC mains power. When a power outage is detected, the system triggers a GSM module (SIM800/900) to send an SMS alert to predefined mobile numbers. Additionally, the system logs outage events and can be integrated with IoT platforms for remote monitoring and historical data analysis. Key Features:  Real-time power monitoring using a voltage sensor.  Instant SMS alerts via GSM when power fails.  Low-cost and energy-efficient design using Arduino.  Expandable for integration with IoT dashboards (e.g., Blynk, ThingSpeak).  Battery backup to ensure functionality during outages. This system provides a reliable and automated solution for homes, industries, and critical infrastructure to mitigate the impact of unexpected power failures.
