Arduino Brewing Water Quality Monitor Kit - TDS, EC & Temp
Arduino Home Brewing Water Quality Monitor Kit - TDS, EC & Temperature
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Great beer, coffee, or kombucha starts with great water. This kit lets you build a portable device that reads your water's total dissolved solids (TDS), electrical conductivity (EC), and temperature-then instantly compares the results against the World Health Organization's drinking water guidelines on a bright 16x2 LCD. No guesswork, no lab.
What You'll Build
You'll assemble and program a handheld water tester around an Arduino Uno. Dip the waterproof DS18B20 temperature sensor and the TDS/EC probe into any water sample. Within seconds, the screen shows real-time TDS in ppm, EC in �S/cm, and temperature in �C, plus a simple pass/fail indicator against WHO's 500 ppm TDS threshold for safe drinking water. It runs on a 9V battery, so you can carry it from your kitchen tap to your brewing setup.
What You'll Learn
- How to read analog signals from a TDS/EC sensor and convert them to ppm and �S/cm
- How to interface a waterproof DS18B20 digital temperature sensor with Arduino's OneWire library
- How to drive a 16x2 character LCD via an I2C backpack to save I/O pins
- How to implement logic that compares sensor data against a stored standard (WHO 500 ppm) and displays a clean visual result

Who This Kit Is For
Home brewers who want to dial in their water profile before mashing coffee or boiling wort will find a daily-use tool. CBSE Class 11-12 students can present this as a physics or chemistry investigatory project on water purity. B.Tech ECE and EEE students tackling sensor labs, Smart India Hackathon water-quality challenges, or ATL Tinkering Lab mentors teaching environmental monitoring will get a ready-to-build kit that demonstrates real-world sensor fusion.
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 inside the box to start a conversation with the AI companion, or send us a photo on WhatsApp - we'll help you trace the issue.
How does the TDS EC sensor measure water quality?
It sends a small AC signal through the electrodes and measures conductivity; that value is converted to TDS (ppm) and EC (�S/cm) using built-in calibration constants in the code you'll upload.
Can I calibrate the sensor for other liquids like coffee or tea?
Yes. The included code files show you exactly where to change the conversion factor, so you can match your own solutions or known calibration fluids.
Is the WHO comparison reliable for Indian tap water?
The threshold of 500 ppm TDS is the WHO guideline value for drinking water palatability. Indian municipal water often varies; the kit gives you a baseline and lets you adjust the limit in code if you prefer a stricter local standard.
Brewing - TDS EC sensor tests water samples and compares to WHO drinking water standard on LCD.
