water level sensor circuit(using bc547 npn transistors) (part1)



the video demonstrates how to create a simple basic 3 level water sensor(high medium and low)
you require 3 npn transitors and 3 leds and 3 resistors as main components.
the base of each transistor acts as different level in the water tank and the leds are connected to emmiter.
