Description

Home power monitoring system - Monitoring energy consumption with better granularity

README

PowerTiger

Overview

This project is an open-source energy monitoring solution designed to track and measure power consumption in a household. The design is centered around the Raspberry Pi Pico W, interfaced with Current Transformer (CT) sensors via a custom PCB. The project is developed using KiCad for PCB design and is part of an open-source hardware (OSH) initiative.

Features

1. Real-time power monitoring: Accurately measure and track power usage in real-time using CT sensors.
2. Wireless communication: The RPi Pico W provides wireless connectivity, enabling easy integration with IoT platforms.
3. Scalable design: Supports multiple CT sensors to monitor different circuits or devices.
4. Open-source hardware and software: The design files and source code are freely available for customization and improvement as part of the OSH initiative.

Project Components

• Raspberry Pi Pico W: The microcontroller at the heart of the project, providing processing power and wireless connectivity.
• Custom PCB: Designed in KiCad, this PCB interfaces with the CT sensors for power measurement of various terminals.
• CT Sensors: Used to measure the current flowing through the electrical wires, providing the data needed for power calculation.
• Software: The firmware is written in CircuitPython, running on the RPi Pico W.
