Smart Automatic Water Dispenser Kit is an innovative DIY STEM experiment that teaches students how magnetic sensors and electrical circuits can automate everyday systems.

When a cup (with a magnet attached) is placed under the dispenser, the system detects it and automatically pumps water. Once the cup is removed, the system stops — just like real smart machines.

Key Features

✔ Automatic water dispensing system

✔ Magnetic sensor (reed switch technology)

✔ Real working water pump

✔ Fun, interactive design (kid-friendly)

✔ Hands-on electrical circuit building

✔ DIY cardboard assembly

How It Works (Scientific Principle)

• Cup contains a magnet

• Magnet activates reed switch (magnetic sensor)

• Circuit closes → water pump turns ON

• Cup removed → circuit opens → pump stops

👉 Based on:

• Magnetism
• Electrical circuits (series connection)
• Automation systems (input → response)

Concepts Taught

✔ Magnetism & sensors

✔ Circuit design

✔ Automation logic

✔ Cause-and-effect systems

✔ Real-life engineering applications

Educational Value 🎓
