Arduino Indoor Radon Proxy Monitor Kit: Build a Basement Radiation Detector and Identify Radon Risk

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

Radon gas, invisible and odourless, accumulates in poorly ventilated basements and underground spaces. By tracking elevated background radiation with a Geiger counter, this kit acts as an indirect radon proxy monitor. You’ll build a battery-operated Arduino logger that records counts per minute, displays them on an OLED screen, and sounds a buzzer when radiation crosses a set limit — a working environmental sensor that mirrors the method used in professional radon surveys.

What You'll Build

You’ll assemble a portable, time-stamped radiation logger. The Arduino reads pulses from the Geiger module, the DS3231 RTC labels each measurement with date and time, and the microSD card saves a CSV log file. Real-time radiation counts appear on the 0.96-inch OLED display, while the active buzzer triggers immediately if CPM exceed the alarm level you define in the code. The battery snap makes the unit standalone, so you can place it in a basement corner and retrieve the data later.

What You'll Learn

• Interface a Geiger tube module with Arduino and convert raw pulses into counts per minute
• Use the DS3231 RTC to keep accurate time across power cycles and log data with timestamps
• Write sensor data to a microSD card in CSV format for spreadsheet analysis
• Program a threshold-based alarm using an active buzzer to signal radiation spikes

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate kit is ideal for CBSE Class 11–12 students investigating environmental physics, B.Tech ECE or EEE learners exploring indoor air quality, and ATL Tinkering Lab teams preparing for the Smart India Hackathon. If you have wired a basic Arduino circuit before, this project will sharpen your data logging and threshold programming skills with a real-world radiation monitoring use case.
