DIY Mosquito Repellent Light with Fan




Mosquitoes are a common problem in homes, especially during summer and rainy seasons. In this DIY project, we will create a Mosquito Repellent Light with a Fan using simple electronic components. This project attracts mosquitoes with light and pushes them away using airflow from a small fan.

This project is simple, low-cost, and perfect for beginners interested in electronics.

Components Required

  • LED Bulb or LED Strip

  • Small DC Fan (5V or 12V)

  • USB Cable or DC Power Adapter

  • Plastic Box or Container

  • Switch (optional)

  • Wires

  • Soldering Iron

  • Glue Gun

Circuit Concept

The idea is very simple:

  • The LED light attracts mosquitoes.

  • The fan creates airflow, disturbing their flight and pushing them away.

  • Both the LED and fan run from the same power source.

You can connect the fan and LED in parallel so both operate at the same time.

Step-by-Step Instructions

Step 1: Prepare the Box

Take a plastic container or small box. Make holes in the front for the fan and small ventilation holes for airflow.

Step 2: Install the Fan

Fix the DC fan inside the box so it blows air outward. Secure it using screws or hot glue.

Step 3: Install the LED Light

Place the LED bulb or LED strip near the fan opening. The light will attract mosquitoes.

Step 4: Wiring

Connect the LED and fan wires together in parallel to the power supply.

  • Red wire → Positive

  • Black wire → Negative

You can add a switch between the power line if you want manual control.

Step 5: Power the Circuit

Use a USB adapter, power bank, or 12V adapter depending on your fan and LED rating.

Step 6: Test the Device

Turn on the power. The LED will glow and the fan will start spinning. Place the device near a window or outdoor sitting area.

Advantages of This DIY Project

  • Low cost project

  • Easy to build at home

  • Safe and chemical-free

  • Good beginner electronics practice

  • Can run on USB power bank

Possible Improvements

You can upgrade the project by adding:

  • UV LED light for better attraction

  • Rechargeable battery

  • Solar panel charging

  • Automatic night sensor

Conclusion

This DIY Mosquito Repellent Light with Fan is a simple and practical electronics project. It is ideal for students, hobbyists, and DIY lovers who want to create useful gadgets at home.

Try this project and share it with your friends or students who are learning electronics.
