Car Parking Sensor HUD
Custom parking sensor and heads-up display for older vehicles
Overview
A custom parking sensor system designed for older cars that lack factory-fitted parking aids. Combines ultrasonic distance sensors with a heads-up display (HUD) to give the driver real-time proximity feedback without looking away from the road.
Technical Details
- ESP32-based controller — handles sensor polling, distance calculation, and display output
- Ultrasonic sensors — multiple rear-mounted sensors for zone-based detection
- Serial communication — sensor data pipeline from microcontroller to display unit
- Custom PCB — designed and fabricated for clean integration into the vehicle
- Low-latency feedback — distance-to-beep mapping with progressive urgency
Outcome
Fully functional prototype installed and tested in-vehicle. Demonstrated proficiency in end-to-end embedded hardware design — from schematic capture and PCB layout through firmware development to physical installation.
