Geiger Counter Radiation Monitor Kit with Arduino Uno
Arduino Geiger Counter Kit — Your Personal Radiation Monitor That Logs Dose Rates to SD
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Assemble a fully functional radiation monitor that detects beta and gamma particles, calculates dose rate in microsieverts per hour, and stores hourly averages with an RTC timestamp onto a microSD card. Whether you want to check antique ceramics, survey your lab, or simply understand environmental radiation, this kit gives you a professional-grade logging tool you build yourself.
What You'll Build
You will create a portable Geiger counter with a bright 16x2 LCD showing real-time counts per minute (CPM) and the biologically relevant dose rate (µSv/hr). The DS3231 real-time clock stamps every logged data point so you can track changes throughout the day or across experiments. All hourly averaged readings save to a microSD card as a CSV file, ready for analysis in any spreadsheet.
What You'll Learn
- Reading pulses from a Geiger-Müller tube and converting CPM to µSv/hr using sensitivity calibration
- Implementing an I2C LCD backpack to display live radiation data and system status
- Logging time-stamped sensor data to a microSD card with the DS3231 RTC
- Soldering through-hole components onto a prototype board to create a permanent, field-ready device

Who This Kit Is For
This intermediate kit suits CBSE Class 12 physics enthusiasts building an investigatory project on background radiation, B.Tech ECE/EEE students needing an instrumentation project, and participants in the Smart India Hackathon or institutional science fairs. ATL Tinkering Labs and college clubs at IIT, NIT, VIT, and BITS will find it an excellent platform for data-logging experiments that combine hardware prototyping with environmental sensing.
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 on the box to access the AI companion, which knows the exact wiring and code for this kit. If you need a human touch, message us on WhatsApp — we reply within hours on business days.
What radiation sources can this detect?
The Geiger tube responds to beta particles (electrons) and gamma photons. You can check uranium glass, old Fiestaware, thoriated welding rods, or monitor ambient background levels. It doesn't detect alpha particles unless the source is extremely close, as the tube window is not mica-thin.
Do I need soldering experience to assemble this?
The kit includes a soldering iron and solder, so no prior gear is needed. The AI guide walks you through every joint. If you're completely new, set aside an extra hour to practice on the proto board before assembling the main circuits.
Can I modify the code to log every minute instead of hourly?
Absolutely. The Arduino sketch is open source and the AI companion will show you exactly which line to change. You can log any interval you like, as long as the SD card has space.
Geiger-Muller tube counts CPM. LCD shows dose rate in µSv/hr. SD logs hourly average with RTC.
