Parking Distance Sensor Pro Kit with Arduino Uno
Parking Distance Sensor Pro Kit with Arduino Uno — Build an Ultrasonic Reverse Parking Aid with LCD Bar Graph
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 backing your car into a tight spot without a second person guiding you. With this kit, you’ll build an ultrasonic distance sensor that reads gaps from 2 cm to 4 meters, displaying the exact distance in centimeters and inches on a bright 16x2 LCD, complete with a moving bar graph. It’s the same principle found in modern reverse parking systems, now on your workbench.
What You'll Build
You’ll assemble a fully functional parking sensor unit that can be mounted temporarily on a wall or held in hand to measure distances in real time. The sensor uses ultrasonic pulses—silent, precise, and safe—and displays readings numerically plus a bar that grows longer as objects get closer. Perfect for demonstrating how autonomous vehicles sense obstacles.
What You'll Learn
- How an HC-SR04 ultrasonic sensor works, calculating distance from time-of-flight
- Integrating an I2C LCD for crisp alphanumeric output without messy wiring
- Writing Arduino code to convert raw sensor data into cm and inches
- Visualizing distance with a dynamic bar graph on the LCD, updating in real time

Who This Kit Is For
Ideal for CBSE Class 11–12 students building a distance measurement physics project, ATL Tinkering Lab members exploring sensor technology, or young hobbyists from age 10 and above eager to understand ultrasonic sensing. B.Tech first‑year students can also use it to grasp Arduino and LCD basics.
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?
Scan the QR code on the box to access your AI build companion—trained on this exact project—or WhatsApp us directly; we’ll walk you through it.
How accurate is the parking distance sensor?
The HC‑SR04 ultrasonic sensor has an accuracy of ±3 mm, providing reliable distance readings for parking guidance. The LCD updates in real time with no noticeable lag.
Can I use this sensor on an actual car?
While this is an educational prototype, the principle is identical to real parking sensors. With proper weatherproofing and a 12V power supply, you can adapt it for a car, but we recommend it for learning and testing first.
What if the LCD doesn’t show anything?
Make sure the I2C backpack is properly connected and the address is set correctly. The AI companion will guide you through troubleshooting, and we can replace any faulty part within 7 days.
Parking — Measure distance from 2cm to 400cm using ultrasonic pulses. Display cm and inches on LCD with bar graph.
