This document describes a high voltage fuse blown indicator system with voice announcement. The system monitors current to two light bulbs using a current sensor and ADC to convert the analog signal to digital. The microcontroller checks if the current increases past a threshold level and announces via speaker if the fuse is blown to automate detection and provide voice notifications of the status.

High voltage fuse blown indicator with voice based announcement system
- 1. HIGH VOLTAGE FUSE BLOWN INDICATOR WITH VOICE BASED ANNOUNCEMENT SYSTEM ABSTRACT Now-a-days technology has developed to a large extend. At the same time the need for systems with automation and high security are preferred. In this project we are indicating high voltage and low voltage of loads by using voice IC. In this project for demo purpose we are using two bulbs as loads. We are using current sensor to sense current consumed by loads and ADC is to convert analog signal into digital. That converted data is given to microcontroller.MC checks whether current values increases from its threshold level or not. If so, then it gives voice announcement by using speaker. BLOCK DIAGRAM
