Automatic Water Level Controller using Arduino & float sensor for Overhead Tank | Arduino Project

In this Arduino project, I have shown how to make an automatic water level controller using Arduino and float sensors. This water level monitoring system will also check the water level in both the overhead tank and underground water tank and accordingly control the water pump automatically.

You can always monitor the tank water level for both the water tank and also control the water pump manually in manual mode.

During this video, I made the automatic pump control circuit on zero PCB using the PCB layout, and also shared the water tank level controller circuit and Arduino source code.

In manual mode, the alarm will ring when the tank is full, and when the water level drop below the threshold limit the pump with automatically turn off.

During the Arduino project video, I covered the following topics:
01:31 Quick demo on Arduino based water level controller.
03:29 Required components for this Arduino project.
03:53 Circuit diagram of the Arduino water level sensor.
05:20 How to make water level indicator on Zero PCB.
06:22 Source code for the Arduino project.
08:43 Connection diagram for Water Pump & Float sensor
09:13 Testing the Arduino-based water level controller circuit.
09:53 Installing the water pump controller and float switch.


Required components for the non-contact liquid level sensor.
1) Arduino UNO or Arduino Nano
2) Float switch sensor 2no
3) 30A 5V SPDT relay module
4) 1k 0.25watt Resistors - 8 no (R1 - R8)
5) 10k 0.25watt Resistors - 4 no (R9 - R12)
6) BC547 NPN Transistor (Q1)
7) LED 5mm - 7no
8) 2-pin Terminal connectors (5 no)
9) 3-pin Terminal connectors (3 no)
10) 5V DC Buzzer
11) Switches - 2no
12) AC to DC converter 5V HLK-10M05 (Optional)

Please refer to the following video on how the float switch works
   • HOW TO INSTALL FLOAT SWITCH FOR WATER...  

Important points:
1. Set the float switch ON and OFF distance as per the water tank height.
2. Use the relay module as per the pump rating. Here I have used 30A 5V SPDT Relay (Active LOW).
3. If there is no water in the underground tank the pump will not start.
4. You can also use Arduino UNO for this Arduino based project.
5. You can either give the AC supply or the 5V DC supply to this circuit.
6. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.

This Arduino-based water level controller will help you to maintain the water level in the tank, also it is very useful to save energy and water resource.

If you face any issues please let me know in the comment section.
