Water Level indicator diagram
Water tank overflow is a common problem which leads to the wastage of water. Though there are many solutions to it like ball valves which automatically stop the water flow once the tank gets full. But being an electronics enthusiastic wouldn’t you like an electronic solution for it? So here is a simple and handy DIY water alarm project tutorial that will guide you to make a circuit which will detect the water level and will raise an alarm upon getting the water tank full or a preset level.
This simple transistor based water level indicator circuit is very useful to indicate the water levels in a tank. Whenever 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 initial three levels (A, B, C), and one Buzzer to indicate FULL level (D). When tanks gets filled completely we get beep sound from Buzzer. If you want to improve the project by adding a display and automatic motor on-off control then you can simply add a microcontroller like Arduino to sense the water changes and control the display and motor accordingly, if you want more details about that project you can check out the Arduino based water level indicator and controller project.
Components Required for Water Level Alarm Circuit
- 4 - BC547 transistors
- 6 - 220 ohm resistors
- 3 - Colour LEDs - red, green, and yellow
- 1 – Buzzer
- 5 - 9v battery + battery clip
- Breadboard
