Log Every Litre: Arduino Water Meter Usage Logger Kit with OLED

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Track your household water consumption down to the litre with this Arduino-powered data logger. The YF-S201 flow sensor measures water passing through a pipe, recording litres per hour with a timestamp from the DS3231 RTC to a microSD card. Each day, view a usage chart on the OLED display to spot patterns and save water.

What You'll Build

You'll assemble a functioning water meter that attaches to a standard 1/2-inch pipe. Once running, it records water flow continuously and stores hourly consumption data on an SD card. The OLED screen shows a daily usage bar chart, so you can instantly see peak usage times and identify leaks or wastage.

What You'll Learn

• Interface a hall-effect flow sensor with Arduino and convert pulses to litres per hour
• Write structured data to an SD card with real-time clock timestamps for accurate logging
• Drive an OLED display to render dynamic bar charts from stored data
• Debug sensor noise and calibrate flow readings for reliable home monitoring
