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.
