Counterfeit Detection UV Scanner Variant 34 Kit with Arduino Mega + LED
Authenticate Currency with Bank-Grade Precision: Arduino Mega UV Scanner Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
With counterfeit notes becoming increasingly sophisticated in India, this kit empowers you to build a professional-grade UV scanner that compares the unique fluorescence signature of each note against a stored template. Using an Arduino Mega 2560, a UV LED array at 395nm, and a BPW34 photodiode array, you construct a system capable of detecting subtle anomalies invisible to the naked eye. Perfect for small business owners, cash handlers, and security enthusiasts who demand reliable authentication.
What You'll Build
A self-contained, portable counterfeit detection device with an OLED display, real-time clock for logging scans, and microSD storage for signature templates. The finished unit scans Indian currency notes under controlled UV light, analyzes the fluorescence intensity pattern from multiple points, and provides a clear pass/fail indication. It's a tool you can use daily to protect your cash from sophisticated forgeries.
What You'll Learn
- Interfacing multiple photodiodes with op-amp signal conditioning for analog sensor arrays.
- Implementing pattern matching algorithms comparing real-time sensor readings against pre-stored digital signatures.
- Using the Arduino Mega's I/O to manage a UV LED array, OLED display, RTC module, and microSD for data logging.
- Soldering and assembling a multi-board prototype into a functional detection system, honing advanced construction skills.

Who This Kit Is For
Designed for advanced hobbyists, engineering students pursuing B.Tech ECE or final-year projects, and professionals in the security sector. If you're participating in Smart India Hackathon challenges on counterfeit detection, or you run a retail business handling large cash volumes, this kit gives you hands-on experience building a real solution. Also ideal for makers from IIT, NIT, VIT, BITS Pilani looking for an intensive embedded systems project.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Our AI companion, accessible via the QR code included in the box, provides step-by-step troubleshooting for this exact build. If you still need help, reach us on WhatsApp for direct engineer support.
Can this scanner differentiate between genuine and high-quality counterfeit notes?
Yes, it compares the fluorescence intensity distribution across eight detection points against a stored template. Advanced counterfeits that mimic visual properties often fail to replicate the exact UV fluorescence pattern, making the scanner highly effective.
Is the template for Indian currency pre-loaded, and can I add other currencies?
The kit includes a microSD with signature templates for current Indian Rupee denominations (Rs. 10, 20, 50, 100, 200, 500). You can calibrate and store your own templates for other currencies by following the provided guide.
Do I need prior experience with Arduino projects to build this kit?
This is an advanced kit; prior experience with Arduino and soldering is expected. You should be comfortable reading schematics and handling analog sensor circuits. Our AI companion assumes intermediate knowledge and focuses on the unique challenges of this build.
