Raspberry Pi 4 ROS2 Parking Sensor Kit - Learn Distributed Sensing
Parking Distance Sensor Kit v3 - Build a ROS2-Enabled Sensor Stack on Raspberry Pi 4
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Assemble a genuine ROS2 Humble sensor suite that streams live distance, environmental, inertial, and camera data over DDS - exactly the architecture used in autonomous parking research. Your Raspberry Pi 4 becomes a multi-topic ROS2 node, ready to feed perception algorithms or a dashboard like Foxglove Studio.
What You'll Build
You'll produce a fully documented ROS2 graph with four active publishers. The HC-SR04 ultrasonic sensor publishes range data at 10 Hz, the DHT22 pushes temperature/humidity, the MPU6050 broadcasts orientation and acceleration, and the Pi Camera Module 3 delivers compressed image streams. All topics are immediately visible in rqt and can be recorded to rosbag for later analysis - giving you a real sensor-fusion backbone for advanced parking-assist or robotics projects.
What You'll Learn
- Publish raw sensor data as standard ROS2 topics (sensor_msgs/Range, sensor_msgs/Imu, sensor_msgs/CompressedImage, and custom messages)
- Configure and test DDS reliability settings for lossless data delivery over a local network
- Monitor live topic rates and link structure with rqt_graph and 'ros2 topic echo'
- Set up a multi-sensor node on Raspberry Pi 4 running ROS2 Humble without overloading the CPU, using optimized camera capture

Who This Kit Is For
B.Tech ECE/EEE students in their third or fourth year who need a complete ROS2 sensor system for capstone or Smart India Hackathon entries. Robotics enthusiasts at IITs, NITs, VIT, or BITS Pilani who want a production-like DDS sensor stack for autonomous parking simulations. ATL Tinkering Lab mentors guiding advanced learners through distributed perception prototyping.
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 inside the box and the AI companion walks you through wiring, code, and ROS2 launch files. If you prefer a human, our WhatsApp support replies within 2 hours on weekdays.
Does the microSD card arrive ready to boot ROS2?
The 64GB card is blank to let you set up the exact Raspberry Pi OS image you want. The AI companion provides a scripted guide to flash the OS and install ROS2 Humble in about 30 minutes.
Can I view the sensor topics on my laptop without an extra display?
Yes. Connect your laptop and the Pi to the same Wi-Fi network, then use Foxglove Studio or RViz2 with ROS_DOMAIN_ID set - the guide includes a one-click configuration.
What if I want to add a second ultrasonic sensor later?
The kit includes extra resistors and jumper wires specifically so you can easily expand to a dual-sensor parking array. The AI companion explains how to duplicate the HC-SR04 node and remap topics.
Parking - Pi 4 runs ROS2 Humble. DHT22, MPU6050, ultrasonic and camera publish as ROS2 topics over DDS.
