## Overview

The Split Single Phase Real Time Whole House Energy Meter by CircuitSetup allows you to monitor your electricity usage remotely via your smartphone. With real-time sampling of two current channels and one voltage channel, it provides precise calculations of active, reactive, and apparent power, along with power factor and frequency. Compact and easy to integrate with Arduino-compatible devices, this energy meter is designed for indoor use and is perfect for tech-savvy homeowners looking to optimize their energy consumption.

## Description

The CircuitSetup ATM90E32 Split Single Phase Energy Meter can monitor the energy usage in your entire home in real time. It can easily be hooked up to an ESP8266 or ESP32 to wirelessly transmit energy usage data into a program like EmonCMS. It can also be used to monitor solar power generation to keep track of how much power you are making.  The ATM90E32 IC from Microchip is versatile and affordable. We’ve put it on a 40x50mm PCB and connected all the useful bits, so it’s easy to hook up to an ESP or Arduino board of choice, current transformers, and an AC transformer (for voltage & powering the board). Next, all you have to do is load the software on your MPU via the Arduino IDE to start seeing how much power your house is using!  Features: Samples 2 current channels & 1 voltage channel (expandable to 2 voltage) Calculates Active Power, Reactive Power, Apparent Power, Power Factor, Frequency, and Temp Uses standard current transformer clamps to sample current Includes buck converter to power ESP8266, or ESP32 (one AC transformer is required, which is used to sample current) Can set warnings for over voltage & sag, over current, and frequency thresholds 2 IRQ interrupts, and 1 Warning output Energy pulse output (pulses also correspond to 4 LED’s) SPI Interface Measurement Error: 0.1% ADC Resolution (bits): 16  Intended for single split phase homes  What you’ll need: Current Transformers: SCT-013-000 (will have to cut off connectors and wire into the boards screw connectors) or Magnelab SCT-0750-100 (must sever burden resistor connection on the back of the board since they have a built in burden resistor) AC Transformer: 9v An ESP32 (ESP8266 or anything else that has an SPI interface) Jumper wires with Dupont connectors to connect the two boards. Software to load on your MPU using the Arduino IDE: EmonESP and ATM90E32_Arduino EmonCMS, ThingSpeak or similar
