Water Tank Level Monitor Kit v2
Build a Remote Water Tank Monitor with Arduino UNO Q and SSH Access
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine checking your overhead tank's water level from a hostel room or a lab bench — no ladders, no guesswork. This kit lets you SSH into a Linux-running Arduino UNO Q to read an ultrasonic sensor and a temperature/humidity module, then toggle a relay that controls a pump or alarm. The STM32 coprocessor handles all real-time I/O, so your commands execute with industrial-grade reliability. Whether for a campus water audit or a Smart India Hackathon prototype, you'll have a tangible IoT device in a single afternoon.
What You'll Build
You will assemble a fully enclosed water tank monitoring station. The HC-SR04 ultrasonic sensor measures water depth with millimetre precision, while the DHT22 captures ambient conditions that affect readings. Through a terminal, you can SSH into the Arduino UNO Q, run a Python script that samples both sensors, and switch the 4-channel relay — all without touching the hardware. This is a real networked automation project, not a toy.
What You'll Learn
- SSH configuration on an embedded Linux board and remote command execution
- Interfacing ultrasonic and digital temperature/humidity sensors over GPIO
- Programming the STM32 coprocessor for deterministic relay control
- Power management with a buck converter and noise filtering using diodes and capacitors

Who This Kit Is For
This intermediate kit is built for B.Tech ECE, EEE, and CSE students working on IoT lab assignments, mini‑projects, or hackathon prototypes like the Smart India Hackathon. It also fits final‑year capstone projects at IITs, NITs, VIT, BITS, and other engineering colleges where a practical demonstration of embedded Linux and remote automation is required. If you understand basic C/Python and have used a terminal before, you're ready.
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 every step, from soldering the prototype board to SSH key setup. If you still hit a wall, message us on WhatsApp and an engineer who built the same kit will reply within a working day.
How does the STM32 interact with the Arduino UNO Q?
The Arduino UNO Q's Linux side handles networking and your SSH sessions, while the onboard STM32 microcontroller manages low‑latency sensor reads and relay switching. A serial protocol bridges the two, and the companion guide provides the firmware and Python libraries to get it running.
Can I extend this to monitor multiple tanks?
Yes. The 4‑channel relay module and spare GPIOs on the UNO Q let you add three more HC‑SR04 sensors. The AI companion includes notes on scaling the setup and modifying the Python script for multi‑tank dashboards.
Do I need prior soldering experience?
Some basic soldering is required to assemble the PCB prototype board and sensor connections. The kit includes a soldering iron and solder wire, and the companion guide has a video tutorial for beginners. Most students complete it on the first try.
Tank Monitoring — SSH into Linux on UNO Q to read sensors and toggle relays remotely. STM32 handles all real-time I/O.
