The ROBODIUM Smart Water Level Pump Kit is a complete DIY automation package designed to automatically monitor water levels and control a motor pump.
Using an Arduino Nano/Uno, water level sensor, and a relay-based pump driver, this kit helps you build a system that automatically turns the pump ON/OFF depending on the tank water level.
The kit also includes an OLED display to show real-time status such as Water Level %, Pump ON/OFF, Low Water Alert, and more.
Perfect for home automation, school/college projects, IoT beginners, and practical real-life applications.
Ideal for:
Automatic Overhead Tank Control
Smart Home Water Automation
Engineering/Diploma Projects
IoT + Embedded System Learning
