ESP32 Parking Sensor Kit - Build a 4-Slot Occupancy Dashboard
ESP32 Parking Sensor Kit: Build a Real-Time Occupancy Dashboard for Four Parking Bays
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You've walked through packed parking structures where drivers circle endlessly, unaware of vacant slots a few metres away. This kit lets you prototype a solution - a miniature multi-bay parking lot that uses four ultrasonic sensors, an ESP32-S3 microcontroller, and a live WiFi dashboard to show which spots are free. It's a hands-on IoT project that mirrors real-world smart parking systems found in malls, offices, and smart city deployments.
What You'll Build
By the end of the 4-5 hour assembly, you will have a working four-bay parking model. Each HC-SR04 sensor continuously measures distance to a vehicle; the ESP32-S3 processes the data and updates an LED strip to show red (occupied) or green (vacant) beside each bay. Simultaneously, a web dashboard served over WiFi displays the real-time occupancy map on any browser-connected device. No external cloud service - everything runs locally on the microcontroller.
What You'll Learn
- Interfacing multiple HC-SR04 ultrasonic sensors with the ESP32-S3 and calibrating threshold distances for reliable vehicle detection
- Programming a deterministic slot-state machine that avoids false triggers and hysteresis
- Setting up an ESP32 as a WiFi access point and serving a responsive HTML dashboard with live status updates
- Soldering and assembling discrete components - resistors, capacitors, and a WS2812B LED strip - onto a prototype PCB for a compact, permanent build

Who This Kit Is For
This intermediate-level kit is designed for CBSE Class 11-12 students pursuing IoT or robotics as a subject, B.Tech ECE/EEE first- and second-year students looking for a solid mini-project, and ATL Tinkering Lab mentors who want a ready-to-assemble IoT demonstration. It also fits neatly into Smart India Hackathon concepts around smart parking and is a popular choice at engineering colleges like VIT, NIT, and BITS Pilani for hackathons and capstone projects.
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?
You can ask the AI companion any question about wiring, code, or calibration. If you need human help, send a photo over WhatsApp and our team responds within a few hours.
Do I need prior soldering experience?
The kit expects basic soldering skills, but the AI companion includes a detailed soldering guide for the PCB. If you've never soldered, consider ordering an extra prototype board for practice.
Can I extend the system to more than four bays?
Yes, the code is modular. You can add more HC-SR04 sensors and adjust the slot-state logic. The ESP32-S3 has enough GPIOs for up to eight bays, and the AI companion will help modify the firmware.
How does the dashboard display work without an internet connection?
The ESP32-S3 creates its own WiFi network. Connect any phone or laptop to that network, open a browser, and the dashboard loads as a local web page - no internet needed.
Parking - Four HC-SR04 sensors on parking bays. ESP32-S3 runs slot-state logic and publishes occupancy map via WiFi dashboard.
