DIY Tree Water Management System Using an Old TV Remote
Have an old TV remote lying around? Instead of tossing it in the trash, you can repurpose it into a remote-controlled tree water management system. This clever DIY hack lets you control water flow to your plants or trees with the click of a button — perfect for gardens, farms, or home plants.
Why This Project?
-
Upcycle old electronics instead of creating e-waste
-
Manage plant watering without going outside every time
-
Save water by controlling irrigation precisely
-
Add a touch of tech fun to your gardening routine
How It Works
The old TV remote sends an infrared (IR) signal, which is received by an IR receiver module connected to a simple control circuit. This circuit controls a water pump or solenoid valve, letting you turn watering on or off from a distance.
Materials You’ll Need
-
Old TV remote (working condition)
-
IR receiver module (TSOP1738 or similar)
-
Microcontroller (Arduino, ESP8266, or any simple controller)
-
Relay module (to control the water pump or solenoid valve)
-
Water pump or solenoid valve
-
Water source (tank or pipeline)
-
Power supply (can be from an old mobile charger)
-
Jumper wires & breadboard (for testing)
-
Soldering iron & solder
Step-by-Step Guide
1. Test the Old Remote
Check if the remote is still transmitting IR signals using your mobile camera — press any button, and you should see a blinking light on your phone screen.
2. Connect the IR Receiver
Wire the IR receiver module to your microcontroller. Connect VCC to 5V, GND to ground, and OUT pin to a digital input pin.
3. Program the Microcontroller
Use Arduino IDE (or relevant software) to read the remote’s signals and assign specific buttons to turn the water pump on or off.
4. Add the Relay Module
Connect the relay module to the microcontroller so it can switch the water pump or valve on/off based on the remote signal.
5. Connect the Pump or Valve
Wire the pump or valve to the relay. Ensure you use proper insulation and safety measures for electrical parts.
6. Power the System
Use an old mobile charger to power the microcontroller and IR receiver. Make sure the pump has the right voltage supply.
7. Test the Watering Control
Press the assigned button on your old TV remote to turn on the pump — water should flow to your tree. Press another button to stop it.
Benefits of This System
✅ No extra gadgets — uses items you already have
✅ Remote-controlled convenience — no need to go outside
✅ Water-saving — only water when needed
✅ Fun DIY project — great for learning electronics
Safety & Maintenance Tips
-
Keep all electronics away from direct water contact
-
Ensure the power supply is stable to avoid damage
-
Regularly clean the pump and valve for smooth operation
Final Words
With just an old TV remote, a few electronic components, and a bit of DIY spirit, you can create a smart water management system for your trees. It’s a perfect blend of technology and gardening, helping you save time, conserve water, and give new life to old gadgets.
