DIY Automatic Touchless Water Tap without Arduino || Smart Tap Using IR Sensor || Eazytronic

Introduction

In this tutorial, you will learn how to create a DIY automatic touchless water tap using an infrared (IR) sensor. This project is a great way to enhance hygiene in your home, as it allows you to operate the tap without physical contact. We will guide you through the materials needed and provide clear steps for assembly, ensuring you can successfully build your own smart tap.

Step 1: Gather Materials

Before starting your project, ensure you have the following materials:

• An IR sensor module
• A water tap (faucet)
• A water solenoid valve
• A power supply (battery or adapter)
• Jumper wires
• A breadboard (optional for testing)
• Soldering tools (if necessary)
• A small enclosure for the components

Practical Tip

: Check compatibility between the solenoid valve and your water tap to avoid any issues during installation.

Step 2: Understand the IR Sensor and Solenoid Valve

• IR Sensor: This device detects motion and can trigger the water flow when it senses an object (like your hands) within a certain range.
• Solenoid Valve: This electrically controlled valve will allow water to flow through the tap when activated by the IR sensor.

Common Pitfall

: Ensure the IR sensor is sensitive enough for your needs; if it’s too weak, it may not function properly.

Step 3: Connect the Components

1. Connect the IR Sensor:

   • Attach the VCC pin of the IR sensor to the positive terminal of the power supply.
   • Connect the GND pin to the negative terminal.
   • Connect the OUT pin to the solenoid valve control circuit.

2. Wire the Solenoid Valve:

   • Connect one terminal of the solenoid valve to the power supply (ensure proper voltage).
   • Connect the other terminal to the OUT pin of the IR sensor.

Practical Tip

: Use a breadboard for testing the connections before final assembly to ensure everything works correctly.

Step 4: Test the System

• Turn on the power supply and test the IR sensor by placing your hands in front of it.
• The solenoid valve should open, allowing water to flow through the tap.

Troubleshooting

: If the system doesn’t work, double-check all connections and ensure the IR sensor is receiving power.

Step 5: Secure the Setup

• Once tested, secure all components in the small enclosure.
• Ensure the IR sensor is positioned to effectively detect hands without obstruction.

Step 6: Install the Tap

• Replace your existing tap with the new automatic one if needed.
• Ensure all plumbing connections are tight and leak-free.

Practical Tip

: Consider using Teflon tape on threaded connections to prevent leaks.

Conclusion

Congratulations on building your DIY automatic touchless water tap! This project not only enhances hygiene but also adds a modern touch to your home. Remember to monitor the system for any maintenance needs. You can also explore integrating additional features, like adjusting the sensor’s sensitivity or adding a timer for automatic shut-off. Happy tinkering!
