Description
ABSTRACT
Water is a vital but scarce natural resource. To prevent water wastage, this water tank overflow indicator comes in handy. It gives audio as well visual alarm whenever the water tank overflows. When water in the tank touches the metal plate sensors, it extends ground to pin 2 of IC1. Now pin 3 of IC1 is at a higher potential than pin 2. The high output of the op-amp generates 3.1V across zener diode ZD1. Melody generator IC2 produces a melody, which drives the transistor to light up LED1 and sound an alarm from the loudspeaker.
