X-Ray Fluorescence Analyser Kit with Arduino Mega
X-Ray Fluorescence Analyser Kit with Arduino Mega — Characterize Materials Using SiPM-Based XRF and MCA on TFT
Every part needed for a working XRF analyser, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Identify the elemental fingerprint of a coin, a rock, or a piece of jewellery with this advanced X-ray fluorescence (XRF) analyser. Using an Americium-241 excitation source and a sensitive SiPM detector, the system captures characteristic X-ray energies and plots a multichannel analyzer (MCA) spectrum on the included 2.4-inch TFT. Designed for serious makers, engineering students, and physics enthusiasts, this kit demystifies nuclear instrumentation and turns your Arduino Mega into a portable material lab.
What You'll Build
You will assemble a lead-shielded sample chamber housing an Am-241 source and a SiPM detector, wired to a precision analog front-end and an Arduino Mega that performs pulse-height analysis. The final instrument displays live X-ray energy spectra on the colour TFT, logs timestamped data to a microSD, and lets you identify elements through their characteristic Kα and Kβ peaks — a compact, albeit low-power, version of benchtop XRF analysers used in scrap yards and geology labs.
What You'll Learn
- Principles of X-ray fluorescence and characteristic X-ray emission lines
- SiPM sensor signal conditioning with multiple LM358 op-amp stages
- Multi-channel analyser (MCA) implementation using an ADS1115 ADC and Arduino
- Safety-aware electronics for radiation-handling instruments, including shielding and high-impedance design

Who This Kit Is For
This advanced-level kit is designed for B.Tech ECE/EEE/Instrumentation students tackling nuclear physics lab projects, participants in the Smart India Hackathon hardware track, and researchers needing a low-cost XRF demonstrator. ATL Tinkering Labs at IITs, NITs, and private universities like VIT or BITS Pilani will find it an invaluable hands-on tool for teaching radiation detection without the university lab’s routine bureaucracy.
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 walks you through each calibration step, from op-amp offset adjustments to peak energy calibration. If you need a human perspective, simply send a WhatsApp message to our support team with a photo of your setup.
Is the Americium source safe to handle?
The kit includes a sealed Am-241 button source (exempt quantity, comparable to a smoke detector) inside a lead-shielded box. Provided you follow the assembly instructions and never remove the source from its holder, the exposure is negligible and well within regulatory limits.
Can this analyser identify specific elements?
With proper energy calibration using known samples (e.g., copper Kα at 8.04 keV), you can identify elements with characteristic lines in the detector’s sensitivity range (roughly 5–30 keV). The TFT displays count bins that correspond to energy, and you can match peaks to reference tables.
Will I need additional tools beyond what's in the kit?
You will need a multimeter for troubleshooting and a basic hand tool kit (screwdrivers, wire strippers) — these are not included. A laptop with Arduino IDE is required to upload the pre-written code, which our AI companion will link you to.
SiPM sensor detects characteristic X-ray energies from samples irradiated by Americium source. MCA on TFT.
