Water Detection and Pumping System Using Arduino

This system is designed to detect the presence of water using two wires (acting as probes) and to control a pump that transfers water from one place to a tank.

⚙️ How the System Works

1. Water Detection Using Two Wires

• The system uses two wires as water level probes:
• One wire is connected to 5V output.
• The other wire is connected to an Arduino digital input pin.
• When water is present, it conducts electricity between the wires, and the Arduino receives 5V.
• If there is no water, the input pin reads LOW (0V).

2. Action When Water is Detected

• If 5V is detected (i.e., water is present), the system:
• Stops the vehicle (if it's a water-collecting robot).
• Turns on the pump.
• The pump sucks the water through a pipe and stores it into a tank.

3. Tank Water Level Detection

• Another pair of two wires is placed inside the tank.
• These wires also use the same method:
• One connected to 5V, the other to an Arduino input pin.
• If water reaches the wires in the tank, the Arduino reads 5V, which means the tank is full.

4. Action When Tank is Full

• If the tank is full:
• The system turns off the pump to stop sucking more water.
• An alarm or buzzer may be activated to alert that the tank is full.

🧰 Components Used

• Arduino Uno
• Wires (used as water level sensors)
• Submersible Pump
• Relay Module (to control the pump)
• Buzzer
• Water Tank
• Power Supply (Battery)

✅ Benefits

• Simple and low-cost water detection system
• Automatically transfers water without human intervention
• Prevents overflow of the water tank
• Can be used in smart irrigation, water-collecting robots, or flood control systems
