Home Brewing Temperature Monitor Kit v3
Home Brewing Water Quality Monitor Kit v3 — Raspberry Pi Pico Multi-Sensor Logger for Brewing
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
For home brewers serious about consistency, water chemistry is everything. This kit packs five precision sensors onto a single 60x60mm PCB, turning a Raspberry Pi Pico into a portable water quality profiler that logs pH, electrical conductivity, dissolved oxygen, temperature and turbidity of your brewing liquor. No more guesswork or separate handheld meters—build one compact unit that tracks your water profile from mash to fermenter.
What You'll Build
A fully enclosed handheld water quality monitor that you can dip into your brewing water, mash tun, or fermenter to instantly read and log five critical parameters. The 0.96-inch OLED displays real-time readings, while the microSD stores timestamped data for later analysis. Powered by a rechargeable 2000mAh LiPo battery, it's completely self-contained and portable.
What You'll Learn
- Interfacing multiple analog sensors (pH, EC, DO, turbidity) with a Raspberry Pi Pico
- Implementing I2C communication for RTC and OLED, and SPI for microSD card logging
- Designing a compact instrumentation PCB layout
- Writing MicroPython scripts for multi-channel data acquisition, calibration, and file logging

Who This Kit Is For
This kit is designed for serious home brewing enthusiasts and engineering students in India—think B.Tech ECE/EEE final-year projects, Smart India Hackathon teams, or advanced tinkerers who want to build a professional-grade water analysis tool. If you’re comfortable with soldering, reading sensor datasheets, and writing MicroPython, you’ll love the depth this project offers.
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?
Your kit includes an AI build companion accessible via QR code, plus WhatsApp and email support. Just ask for help with calibration or wiring, and get step-by-step guidance.
Do I need to calibrate the sensors?
Yes. The pH, EC, and DO sensors require calibration with standard buffer solutions (not included). The AI companion provides detailed calibration procedures and MicroPython calibration code examples.
Can I submerge the entire unit in water?
The waterproof enclosure protects the electronics from splashes, but the sensors themselves are water-resistant only at their tips. Avoid fully submerging the enclosure.
What’s the soldering requirement?
You'll solder all components onto the prototype boards. The kit includes a basic soldering iron and solder wire. Expect soldering through-hole and some SMD pads for the PCB-mounted sensors.
