Visitor Counting Door Frame Kit with Arduino Uno + LED
Track Entry and Exit Automatically with the Arduino Uno Visitor Counting Door Frame Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine knowing exactly how many people enter and leave your lab, workshop, or store every day, with data logged automatically. This kit enables you to build a sophisticated door frame visitor counter using two sets of IR break beams to distinguish direction, an Arduino Uno to process signals, a DS3231 real-time clock to timestamp daily counts, and an SD card to store records. A 0.96-inch OLED provides real-time entry and exit tallies at the door itself—a fully functional home automation tool.
What You'll Build
You'll assemble a dual-beam IR sensor array that mounts on a door frame, differentiating between people entering and leaving by their beam-breaking sequence. The system logs every crossing event with a time stamp to an SD card, and simultaneously displays the live count on an OLED. You'll have a reliable occupancy monitor ready to mount and use.
What You'll Learn
- Design and calibrate IR break-beam sensors using LM393 comparators to reliably detect object passage
- Program Arduino to interpret sensor sequencing and differentiate entry from exit
- Integrate a DS3231 real-time clock module to timestamp events and log daily counts
- Write data to a MicroSD card in a structured format for later analysis

Who This Kit Is For
This advanced kit is designed for B.Tech ECE/EEE students building semester projects, Smart India Hackathon teams needing a reliable occupancy counter, and hobbyists prototyping home automation systems. It also fits workshop and ATL Tinkering Lab setups where durable instrumentation is needed. Perfect for final-year projects at IITs, NITs, VIT, or BITS Pilani.
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?
Compoden's AI build companion, accessible via QR code on the box, guides you step by step. You can also message us on WhatsApp for personalized human support.
How accurate is the entry/exit distinction?
The dual IR beam design uses fixed spacing and timing logic to achieve near-perfect direction detection once sensors are correctly aligned. The companion app walks you through precise calibration.
Can I use this kit in bright sunlight or outdoors?
The IR LEDs are modulated to reject ambient noise, but direct sunlight can saturate photodiodes. The AI guide explains shielding techniques; for outdoor use, consider adding an IR filter or housing.
Is soldering experience required?
Yes, the sensor board assembly requires soldering. The kit includes an iron, and the companion shows essential techniques step by step—making it an excellent way to practice soldering skills.
IR break beam at door top counts entries and exits separately. Daily count logged to SD. OLED shows live total.
