Build an Indoor Radon Proxy Monitor with Arduino and a Geiger Counter Module

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Basements and ground-floor rooms can accumulate radon gas — a silent, long-term health risk. Because direct radon meters are expensive and short-lived, this kit builds an indirect proxy monitor. A Geiger counter module measures ambient radiation levels; when radon decay products build up, background radiation rises, giving you an early warning that your indoor air may need ventilation.

What You'll Build

You'll assemble a compact environmental monitor that reads radiation counts per minute from a Geiger tube, timestamps every reading with a real-time clock, logs the data to a microSD card, and displays live CPM on an OLED screen. An active buzzer sounds an alert when radiation crosses a threshold you set — turning raw sensor data into actionable basement safety information.

What You'll Learn

• Interfacing a Geiger counter module with Arduino Uno for pulse counting
• Integrating a DS3231 real-time clock to tag each radiation sample precisely
• Writing timestamped sensor data to a microSD card for offline analysis
• Configuring threshold-based alerts with an active buzzer and OLED display

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for CBSE Class 11–12 science students exploring environmental monitoring projects, B.Tech ECE/EEE undergraduates prototyping sensor systems for the Smart India Hackathon, and ATL Tinkering Lab mentors looking for a hands-on radiation data logger. Also suitable for hobbyists at IIT/NIT/VIT/BITS maker spaces who want to understand indoor air quality beyond CO2.

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.
