Motion-Activated Data Logger Kit with Arduino Uno, RTC & OLED

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

Walk into a room, and this logger instantly records the moment. Every motion detected by the HC-SR501 PIR sensor fires a timestamped entry - with date, hour, minute, and second from the DS3231 RTC - straight to a microSD card. Simultaneously, the OLED screen increments a live event count. It's a compact, self-contained data capture unit you can mount near a doorway, place in a lab, or deploy for wildlife observation, with no laptop needed once powered by a 9V battery. This kit transforms that concept into a working prototype in under five hours, with a pre-tested set of components and step-by-step AI support.

What You'll Build

You'll assemble a standalone data logger on a breadboard. When motion is detected, the Arduino reads the PIR signal, queries the real-time clock for an exact timestamp, writes a line to a CSV file on the SD card (date, time, event), and updates the number shown on the 0.96-inch OLED. The resulting device runs on a 9V battery, letting you place it anywhere, gather data, and later retrieve the SD card to analyze motion patterns in a spreadsheet.

What You'll Learn

• Interfacing a PIR motion sensor with Arduino and configuring sensitivity and delay
• Programming file creation and data logging to a microSD card module
• Setting and reading the DS3231 real-time clock for accurate event timestamps
• Displaying live variables on a 0.96-inch OLED screen using I2C communication

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit fits CBSE Class 11-12 students who need a sensor-based data logging project, B.Tech ECE/EEE undergraduates prototyping for a lab assignment, Smart India Hackathon participants looking for a reliable motion capture module, and ATL Tinkering Lab educators teaching real-world sensor integration. If you're 15-18 and have worked with an Arduino before, the intermediate wiring and code will stretch you just enough without overwhelming.

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.
