Smart Garage Parking Indicator with the Arduino Uno IR Break Beam Kit
Build a Smart Garage Parking Indicator with the Arduino Uno IR Break Beam 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.
Your garage tells you when it's full - with a glowing LED outside and a timestamp log of every entry. This kit shows you how to build a reliable vehicle presence detector using an infrared break beam across the garage entrance, an Arduino Uno, and simple logic. No more stepping out to check after parking; a clear red or green light does the thinking for you.
What You'll Build
A module that sits across your garage doorway: when the IR beam is broken by a vehicle entering or exiting, the system toggles an outdoor LED (red for occupied, green for free) and records the event with the exact time from the DS3231 real-time clock. You'll have a working parking occupancy detector you can mount and use daily - with a clear visual indicator that spares you the guesswork.
What You'll Learn
- Working with IR transmitters and photodiodes to create a reliable break beam sensor
- Interfacing a DS3231 real-time clock with Arduino for accurate timestamping
- Writing condition-based logic to track vehicle entry/exit and toggle output LEDs
- Debugging sensor alignment and thresholding using a breadboard prototype

Who This Kit Is For
This kit suits electronics hobbyists aged 15 and up - especially CBSE Class 11-12 students working on physics or computer science projects, B.Tech ECE/EEE undergraduates building sensor-based prototypes, and ATL Tinkering Lab participants who need a dependable parking sensor for school innovation challenges. It's also a great practical demonstration for engineering design courses at IITs, NITs, VIT, and 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.

How do I align the IR beam across my garage entrance?
The kit includes a positioning guide. Use the indicator LEDs to visually confirm beam alignment, then fine-tune the comparator threshold until the photodiode reliably detects a break.
Does the detector work in bright sunlight?
The IR break beam design inherently rejects most ambient light, but for best results mount the receiver in a shaded spot. The LM393 comparator helps filter out background IR noise.
Can I log the occupancy data to a computer?
The DS3231 RTC timestamps every entry and exit. You can add an SD card module (not included) to store logs; the Arduino code includes comments to guide that extension.
IR break beam at garage entrance detects vehicle. LED outside shows occupancy. Count logged.
