🧼 Arduino COVID Disinfection Box
Stay Safe. Sanitize Smart. Powered by Arduino.
Remember the early days of COVID-19? We were all wiping down groceries, sanitizing packages, and nervous about touching just about anything.
While the world has moved on, safety and hygiene remain top priorities — and that’s where the Arduino COVID Disinfection Box comes in!
This DIY box doesn’t just sanitize your items. It detects when something is placed inside, starts an automated disinfection cycle, and ensures you’re never exposed to harmful UV or chemicals unnecessarily.
Simple, safe, and smart — that’s the future of hygiene.
💡 Why Make a Disinfection Box?
Manual disinfection can be:
- Time-consuming
- Inconsistent
- Sometimes unsafe (e.g. overexposure to UV light)
This Arduino-powered box takes care of all that by:
- Using UV-C light (or mist/spray sanitizer)
- Automatically starting/stopping based on item detection
- Giving audio or visual alerts when the cycle is complete
- Keeping your hands and health protected
Whether it’s a mobile phone, mask, wallet, or delivery package, this project ensures your daily items stay germ-free.
🧰 What You’ll Need
| Component | Purpose |
|---|---|
| Arduino Uno/Nano | Main controller |
| IR Sensor / Ultrasonic | Detects item placed inside |
| UV-C Lamp / Spray Pump | Disinfects the item (choose method) |
| Relay Module | Controls the UV light or pump |
| Buzzer / LED | Alerts on cycle start/end |
| Timer Logic | Defines how long the disinfection lasts |
| Enclosure Box | Housing for the items and electronics |
| Safety Switch (optional) | Ensures UV doesn’t run with lid open |
⚠️ UV-C Warning: UV-C light can be harmful to skin/eyes. Always use a closed box with interlock or safety switch to avoid exposure!
⚙️ How It Works
- User opens box and places an item inside
- IR sensor detects presence
- Arduino triggers UV-C light or disinfectant spray
- A timer (e.g. 20–30 seconds) controls the disinfection duration
- LED or buzzer notifies when it’s safe to remove the item
- UV turns off, and the box waits for the next item
Totally contactless. Super efficient.
🔒 Key Safety Features
- 🔐 Lid detection: Disinfection only works when the lid is closed
- 🚫 Automatic shut-off if sensor detects lid open mid-cycle
- ⏲️ Timer-controlled disinfection to prevent overexposure
- 🔊 Buzzer + LED alerts for user-friendly feedback
This makes it ideal for home, offices, clinics, or schools.
🧠 What You’ll Learn
This project teaches you:
- How to control relays for high-voltage UV lights
- Use of IR or ultrasonic sensors for item detection
- Implementing safety logic in embedded systems
- Timer-based control using Arduino millis() or delay()
- Real-world hygiene automation with IoT potential
It’s perfect for students, makers, or even small businesses looking to create their own sanitizing stations.
✨ Optional Upgrades
Take your box to the next level with these ideas:
- 🌐 Add Bluetooth / WiFi to log disinfection cycles
- 📱 Integrate an app or LCD screen for user instructions
- 🌡️ Add a temperature sensor for added virus control
- 📸 Include a camera module for cycle snapshots
- ☁️ Upload data to cloud dashboard for hospitals or labs
🌍 Why It Matters
While COVID may not be in the headlines daily, hygiene still matters — especially in high-traffic, public, or healthcare settings.
This box isn’t just a school project — it’s a tool that can:
- Prevent virus spread
- Improve safety in shared environments
- Encourage innovation in health-tech
- Be deployed in homes, delivery points, or shared gadgets
🛠️ Building Steps Overview
- Build or repurpose a closed box
- Wire up UV lamp/spray with relay module
- Install IR/ultrasonic sensor inside
- Connect all to Arduino with proper logic
- Add safety switch on lid (magnetic/reed switch recommended)
- Upload the code and test cycles with small items
