The ROBODIUM Aqua Monitor Kit is a complete DIY water-flow measurement and monitoring system designed for students, hobbyists, and automation learners.
Using the YF-S201 Water Flow Sensor, the kit accurately measures the rate and volume of water passing through a pipe. The readings are processed by an Arduino Nano and displayed on either a 16×2 I2C LCD or a compact OLED display, making it suitable for home automation, smart irrigation, water usage tracking, and educational projects.
The kit includes all essential components—power supply options, breadboard, buzzer alarm, and wiring accessories—allowing you to build a real-time water monitoring device with ease.
Ideal for school projects, engineering labs, IoT prototypes, and household water-saving systems.
