SMART VOLTAGE DETECTION AND PROTECTION BOX FOR PREVENTION OF ELECTROCUTION USING ESP32 AND GSM

This paper presented a Smart Voltage Detection and Protection Box that detects unsafe voltage near electric poles and responds without human intervention. The ESP32 compares the sensor reading with a threshold, the relay disconnects the supply, the GSM module alerts the authorities and nearby users, and the buzzer warns the public. The prototype performed all three actions correctly when a fault was simulated. The box is low cost, easy to install and runs on battery backup, so it suits farms, cities, industrial areas, construction sites, public places and disaster-prone regions. Future work will add IoT cloud monitoring, GPS location of the faulty pole, LoRa or NB-IoT links as an alternative to GSM, a solar supply and machine learning for predicting faults, together with measured response time and accuracy figures.
