Counterfeit Detection UV Scanner Kit with Arduino Mega + LED
Build a Counterfeit Currency Detector with the UV Scanner Kit (Arduino Mega)
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit turns an Arduino Mega into a field-ready counterfeit detection system that scans Indian currency notes under 395nm UV light, reads the distinct fluorescence emission patterns, and instantly verifies authenticity against stored signature templates. Whether you're equipping a rural bank branch, prototyping a fintech security device, or building an advanced engineering capstone, this system delivers lab-grade discrimination without commercial scanner costs.
What You'll Build
A standalone UV fluorescence scanner that illuminates notes with an array of eight high-intensity UV LEDs, captures the returned light through eight photodiodes, conditions the signals with precision op-amp stages, and digitizes the fluorescence profile. The Arduino Mega compares the acquired pattern to genuine templates stored on a microSD card, displays a pass/fail judgment on a crisp OLED screen, and timestamps every scan via an integrated real-time clock for an auditable verification trail.
What You'll Learn
- Designing eight-channel UV photodiode amplifiers using LM358 op-amps for low-level light detection
- Implementing fluorescence pattern matching algorithms on Arduino Mega that tolerate natural note variations
- Integrating a DS3231 RTC and OLED to build a complete, standalone inspection terminal
- Constructing a rugged, enclosed prototype with proper grounding and noise immunity for real-world reliability

Why Buy This Kit Instead of Sourcing Parts Separately
| Factor | Sourcing Separately | Compoden Kit |
|---|---|---|
| Compatibility checks | You verify UV LED wavelength, photodiode spectral response, and op-amp gain matching | Pre-tested as a system; LEDs and photodiodes matched for 395nm fluorescence detection |
| Build support | Scattered tutorials and forum posts | AI companion trained on this exact project, guiding fluorescence calibration |
| Time to first working build | Days of debugging signal noise and false positives | Hours, with step-by-step calibration guide and pre-verified template logic |
| Shipping coordination | Multiple sellers, delays, possibly missing components | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
Final-year B.Tech and M.Tech students in electronics, embedded systems, or instrumentation who need a security-themed capstone project; banking and fintech professionals prototyping low-cost counterfeit detection devices for rural branches; Smart India Hackathon teams tackling fake currency challenges; and advanced hobbyists who want to master multi-channel fluorescence sensing and pattern recognition.
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?
Scan the QR code inside the box to start a chat with the AI build companion that knows this scanner inside out, or ping us on WhatsApp for human backup within hours.
How do I collect the fluorescence template from a genuine note?
The AI companion walks you through placing a brand-new, authenticated currency note under the UV array, capturing its emission profile, and saving it as the master template on the microSD card. You can store multiple denomination templates.
Will the scanner work with currencies other than Indian Rupees?
Yes, if the currency exhibits a UV fluorescence feature. You’ll need to capture the fluorescence template of the authentic note following the same calibration process. The sensor array is wavelength-agnostic within the UV range.
What level of soldering experience is required for this advanced kit?
You should be comfortable soldering through-hole components and working with multi-board interconnects. The kit includes a soldering iron and solder wire, and the AI companion offers visual guidance for all critical solder joints.
