Brief
This Model includes set of four wires which are connected to individual BC547 Transistors. These two set of wires needs to be dropped inside a water tank as per the heights. As we keep filling the tank with water. Based on individual levels of water signals will be passed via those wires to the transistor. The transistor will turn on based on the water levels and is indicated by the LED on the Board. Once the water level reaches at the max level. The Alarm indicating Overflow of Water.

Uses

The model emphasis on the importance of Automating the Water Level to avoid wastage of the same
