Inductive Wireless Power Meter Kit with Arduino Uno — See Exactly How Efficiently Wireless Energy Transfers

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

Watch electricity jump through thin air and light up an LED — then put numbers to the magic. This inductive power meter uses two precision INA219 sensors to measure exactly how much DC power enters the transmitter coil and how much reaches the receiver. The difference is displayed in real time on a crisp OLED screen, turning a physics demonstration into a hands‑on data science experiment.

What You'll Build

A dual‑sensor wireless power analyser on a breadboard. When you align the coils, the receiver side LED glows, while the OLED cycles between transmitted power, received power, and efficiency percentage. You’ll have a standalone meter that works with any pair of inductive coils — plug in different loads, vary the distance, and watch the numbers change.

What You'll Learn

• How electromagnetic induction transfers energy without wires and why alignment and distance matter
• Using INA219 current/voltage sensors to capture precise DC power data on both sides of the link
• Multiplexing two I2C sensors through a TCA9548A to avoid address conflicts on a single Arduino
• Calculating real‑time efficiency and formatting live readings on a 0.96‑inch OLED display

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for students and hobbyists exploring electromagnetic induction. CBSE Class 8‑12 students can use it for physics practicals and investigatory projects, while ATL Tinkering Labs get a ready‑made demo on energy loss. First‑year B.Tech (ECE/EEE) learners will appreciate the hands‑on I2C multiplexing challenge, and it fits right into Smart India Hackathon concept prototypes involving wireless energy monitoring.

Built and Backed by Compoden
