Microhydro Turbine Monitor Kit — Real‑Time RPM and Power Display with Arduino

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

Turn a small water wheel into a digital classroom experiment. This kit lets you build a monitor that reads how fast the turbine spins thanks to a Hall sensor, and how much electricity it generates—measured after the AC is rectified into DC using the INA219 sensor. The readings appear live on an OLED screen. Perfect for understanding renewable energy at the circuit level, whether you’re tinkering with a pico‑hydro setup or demonstrating power generation in a school project.

What You'll Build

You’ll assemble a standalone monitor that attaches to a water turbine (not included). A magnet on the wheel triggers the Hall sensor, and the Arduino calculates RPM. The INA219 module measures the rectified DC output, showing voltage, current, and power on the OLED. The result is a dashboard that tells you exactly how your mini hydro generator is performing—whether it’s powering an LED or charging a battery.

What You'll Learn

• Interface a Hall effect sensor to count pulses and convert them to RPM
• Use the INA219 to measure voltage, current, and compute DC power
• Build a bridge rectifier with 1N4007 diodes to convert AC from a generator to DC
• Program an Arduino Uno to read sensors and update an OLED display

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Young explorers (ages 8+) who want to connect a real water wheel to electronics, CBSE Class 11–12 students demonstrating energy conversion for physics projects, ATL Tinkering Lab facilitators introducing renewable energy monitoring, and B.Tech ECE/EEE undergraduates prototyping a simple SCADA‑like sensor interface. If you’re preparing a model for Smart India Hackathon or a college mini project, this kit gives you a working energy dashboard without designing every circuit from scratch.
