Track Water Usage with Arduino Uno Logger Kit - OLED Chart & SD Logging
Track Every Litre: Arduino Uno Water Usage Logger Kit with OLED Chart and SD 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.
Ever wondered exactly how much water your garden, school lab, or household tap consumes each hour? This kit lets you build a precision water meter that records every litre with a YF-S201 flow sensor, timestamps it with a real-time clock, and logs the data to an SD card for later analysis. A daily usage chart appears on a crisp OLED display, giving you instant visibility into your water footprint.
What You'll Build
You'll assemble a compact, Arduino-powered data logger that screws directly onto a 1/2-inch water line. The system detects flow pulses from the YF-S201, converts them to litres per hour, and appends each reading to a CSV file on the microSD card with the exact date and time from the DS3231 RTC. Press a button, and the 0.96-inch OLED renders a bar chart of your last 24 hours of consumption - perfect for spotting leaks or tracking usage patterns.
What You'll Learn
- Interface a Hall-effect flow sensor with Arduino and calculate volumetric flow rate from pulse frequency.
- Integrate a DS3231 real-time clock to timestamp every data entry with second-level accuracy.
- Write sensor data to an SD card in a structured .CSV format for easy import into Excel or Google Sheets.
- Generate a dynamic bar chart on an OLED screen that visualises hourly water usage over a day.

Who This Kit Is For
This kit is ideal for CBSE Class 11-12 students building data logging projects, B.Tech ECE/EEE first-years prototyping smart metering systems, and ATL tinkering lab mentors running water conservation challenges. Hobbyists exploring home automation will appreciate the instant chart and CSV export for integrating with smart home dashboards.
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 to chat with the AI companion trained on this specific logger. It can walk you through wiring, code debugging, or calibration. Human support via WhatsApp is also available.
Can I use this kit to measure water flow at mains pressure?
Yes, the YF-S201 sensor operates from 0.3 to 6 litres/min and withstands up to 1.75 MPa, making it safe for most household mains.
Does the kit include a microSD card?
No, you'll need to supply your own FAT32-formatted microSD card (up to 32 GB). Any standard card works perfectly.
Can I view weekly or monthly charts on the OLED?
The default code generates a 24-hour bar chart; with minor code tweaks (which the AI companion can guide), you can extend it to show weekly averages or monthly totals.
YF-S201 flow sensor logs litres consumed per hour to SD card with RTC. Daily usage chart on OLED.
