Raspberry Pi 4 ROS2 Sensor Hub Kit - Publish Real-Time Sensor Data as ROS2 Topics
Raspberry Pi 4 ROS2 Sensor Hub Kit - Publish Real-Time Sensor Data as ROS2 Topics
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a Raspberry Pi 4 into a fully functional ROS2 sensor node running Humble Hawksbill. DHT22 temperature/humidity, MPU6050 inertial measurement, HC-SR04 ultrasonic distance, and Pi Camera Module 3 all stream live data as standard ROS2 topics over DDS middleware. This is the sensor backbone for robotics prototypes, autonomous platforms, swarm research, and smart environment monitoring-ready to plug into your ROS2 ecosystem.
What You'll Build
You'll wire and program a multi-sensor publisher node that broadcasts environmental, motion, and visual data simultaneously. The system demonstrates reliable many-to-many communication without a central broker, giving you a drop-in sensor suite for any ROS2 robot. View live topic data via ROS2 CLI and visualize sensor feeds in RViz within hours of unboxing.
What You'll Learn
- Install and configure ROS2 Humble on Raspberry Pi 4 with Ubuntu Server
- Interface I2C sensors (MPU6050) and GPIO-based DHT22 plus ultrasonic via Python libraries
- Create ROS2 publisher nodes and define custom message structures for sensor data
- Use DDS security and QoS profiles, visualize topics in RViz, and monitor with rqt_graph

Who This Kit Is For
Designed for advanced undergraduate and graduate students-B.Tech ECE, EEE, CS, and robotics stream-at IITs, NITs, VIT, BITS Pilani, and engineering colleges across India. Perfect for Smart India Hackathon teams needing a ready ROS2 sensor suite, research labs prototyping autonomous systems, and ATL mentors running advanced sensor-integration workshops. Requires basic Linux and Python familiarity; ROS2 experience is not assumed.
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 to launch the AI companion, which has seen every wiring diagram and code file for this project. For human backup, drop a WhatsApp message with a photo of your setup-we respond within hours.
Does the kit include ROS2 pre-installed on the SD card?
No, you'll flash the blank 64GB microSD with Raspberry Pi OS and install ROS2 Humble yourself. Our guide walks you through every terminal command; the AI companion can troubleshoot installation issues live.
Can I use this with ROS2 Foxy or Galactic instead of Humble?
The kit is tested on Humble Hawksbill, but the sensor nodes use standard ROS2 Python APIs. The AI companion can point out API differences if you need to adapt, and we recommend Humble for its long-term support.
Do I need a monitor, keyboard, and mouse to set up the Pi?
Initial headless setup over SSH is fully covered-you'll only need another computer. A monitor helps for first-time Ubuntu configuration, but our instructions include VNC remote desktop alternatives.
Pi 4 runs ROS2 Humble. DHT22, MPU6050, ultrasonic and camera publish as ROS2 topics over DDS.
