Compact Lab-on-Chip Sensor Array
Compact Lab-on-Chip Sensor Array Kit for Raspberry Pi Pico Water Logging
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit condenses a full environmental monitoring station onto a 60x60mm PCB. You’ll build a portable device that samples water and logs pH, electrical conductivity, dissolved oxygen, temperature, and turbidity — a profile that research labs, agricultural projects, and Smart India Hackathon teams need. With the Pico at its core, you’re constructing a self-contained data logger that can run on a LiPo for field deployment.
What You'll Build
A handheld or waterproof-enclosed multi-parameter water profiler that records timestamped sensor readings to a microSD card. The 0.96-inch OLED displays real-time values, while the RTC stamps each entry — producing CSV logs ready for analysis. You’ll solder and integrate all modules onto a compact board, learning surface-mount and through-hole assembly for miniaturized designs.
What You'll Learn
- Calibrating electrochemical sensors (pH, DO, EC) for precise water analysis
- Programming a Raspberry Pi Pico in MicroPython/C++ to poll multiple analog and digital sensors simultaneously
- Designing a low-power data logger with RTC, microSD, and battery management for field deployments
- Building a rugged enclosure and miniaturizing a multi-sensor instrument

Who This Kit Is For
This advanced kit is built for B.Tech students (ECE/EEE) designing final-year environmental monitoring projects, teams participating in Smart India Hackathon or similar competitions needing rapid prototyping, and researchers at IITs, NITs, VIT, BITS looking for a compact multi-sensor logger. CBSE Class 11-12 students with strong electronics skills will also find it a challenging step up from basic Arduino kits.
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 on the box to access the AI build companion for step-by-step guidance; you can also reach us on WhatsApp for direct help.
Can I deploy this kit in a lake or river?
The waterproof enclosure protects the electronics, and the sensors are designed for immersion. You’ll need to secure the device and use the LiPo battery for standalone logging.
Do I need prior experience with Raspberry Pi Pico?
Yes, this is an advanced kit. Familiarity with MicroPython or C/C++ on the Pico and basic soldering is assumed. Our AI companion will guide you through the entire sensor integration and calibration.
How accurate are the readings?
The modules come pre-calibrated at the factory; the AI companion walks you through field calibration with standard buffer solutions for the highest data quality, making it acceptable for research-grade educational projects and hackathon submissions.
Five sensors on a 60x60mm PCB: pH, EC, DO, temperature and turbidity. Pico logs water quality profile.
