How to Make Simple Water Level Indicator Alarm at Home | Homemade Water Tank Alarm DIY Project

Simple Water Level Indicator Alarm or simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank. Whenever a tank gets filled, we get alerts on particular levels. Here we have created 4 levels (low, medium, high and full), we can create alarms for more levels. We have added 3 LEDs to indicate the initial three levels (A, B, C), and one Buzzer to indicate FULL level (D). When tanks get filled completely we get beep sound from Buzzer.
