4-Level water level indicator kit

PROCESS INVOLVED IN 4-Level water level indicator kit:

4-Level water level indicator kit is analog switch loss the triggering pins 5, 6, 12 and 13 triggered through the conducting property of water (although water is e non conductor salts dissolved makes it conductive). once the approximate level is reached the corresponding triggering  pins gets triggered and the corresponding  LED s  will glow as they get the grounding path once the final level is reached both  the level full LED and the transistor gets the high level to trigger a buzzer relay.

1. buzzer
2. resistors
3. pbt
4. capacitors
5. pcb board
6. 4148 diode
7. IC
8. IC base
9. red LED s
