SSH Remote Lab Instrument Controller
SSH Remote Lab Controller Kit: Secure Linux Access to Sensors and Relays on Arduino UNO Q
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Step into the world of hands-off instrumentation. This kit guides you through building a network‑connected controller where the Arduino UNO Q runs a lightweight Linux environment, STM32 handles real‑time I/O, and you read sensors or toggle relays entirely over a secure SSH connection. It is the perfect foundation for monitoring experiments from a hostel room, automating a campus lab, or developing a remote test rig without ever touching physical buttons.
What You'll Build
You will assemble a compact board inside a durable enclosure that, once powered on, becomes a dedicated lab server. Open a terminal on your laptop or phone, SSH into the UNO Q, and instantly retrieve temperature/humidity from the DHT22, distance from the HC-SR04, or switch any of the four relays. The STM32 coprocessor guarantees deterministic sensor reads and relay actuation even under heavy Linux load. The result is a production‑style remote instrument you can control from anywhere on the network—or across the internet with standard port forwarding.
What You'll Learn
- Setting up a Linux SSH server on an embedded board and securing access with keys
- Interfacing DHT22 humidity/temperature and HC-SR04 ultrasonic sensors with STM32 via the Arduino UNO Q
- Controlling a 4‑channel relay module through shell commands to switch external devices like pumps or lights
- Deploying a remote monitoring system with data logging, power regulation using a buck converter, and remote scripting

Who This Kit Is For
Designed for B.Tech ECE and EEE students executing final‑year projects, Smart India Hackathon teams prototyping remote automation, and research scholars who need a reliable SSH‑controlled data logger. It fits ATL mentors guiding advanced college‑level work and makers who have outgrown basic Arduino kits and want to dive into embedded Linux and real‑time control without starting from scratch.
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?
The AI companion covers all steps, from soldering to SSH configuration. If you need a human, our WhatsApp support line has seen this exact kit many times and will guide you to a working build quickly.
Do I need a static IP or cloud server to access the controller remotely?
Not at all. It works on your local Wi‑Fi out of the box. For remote access from outside the network, we provide clear instructions to set up secure tunnels using services like ngrok or Tailscale—no static IP required.
Is the soldering iron included, and do I need previous experience?
Yes, a basic soldering iron and solder wire are in the box. The accompanying AI guide walks you through every joint on the prototype boards, making this an excellent project to build or sharpen your soldering skills.
Can this kit safely control high‑voltage lab instruments?
The 4‑channel relay module is rated for 250V AC at 10A, so it can switch small heaters, pumps, or solenoid valves. Always follow electrical safety norms and preferably have a faculty supervisor review your high‑voltage wiring.
SSH into Linux on UNO Q to read sensors and toggle relays remotely. STM32 handles all real-time I/O.
