Open Energy Monitor Esp32

It can save electricity to help you to save money.

Open energy monitor esp32.

An in depth look at the basic principles of electricity monitoring sustainable energy and more. The emontx v3 uses a 3 3v regulator so it s v cc and therefore aref will always be 3 3v regardless of battery voltage. Exploring the context of renewable energy and zero carbon energy use. Wiring up the circuit.

It measures current but uses an assumed fixed value for voltage 230v if you re in the uk and calculates apparent power. The esp32 is a no brainer for me because i ve used it before on small projects. This guide details how to build a simple energy monitor on a breadboard that can be used to measure how much electrical energy you use in your home. Esp32 has both wifi and bluetooth built into it whereas an arduino uno doesn t.

There are power guzzlers in every household that go about their business unnoticed such as the old electric cooker the tv in stand by mode and illumination with conventional light bulbs. This project creates a real power energy monitor using a nodemcu module with esp8266 12 and ads1115. Der esp32 verkraftet jedoch maximal 3 3v am analog eingang. You can still use the arduino ide to program it by installing the esp32 board in the ide s boards manager.

Open source home energy meter based on the esp32 the home energy meter will hook up to the electrical distribution panel in your home to monitor power usage for the entire panel and a few key branch circuits. It also has a larger memory and faster clock speed. Das prinzip lässt sich 1 1 vom aufbau eines arduinos übernehmen. The standard emontx v3 uses 22ω burden resistors for ct 1 2 and 3 and a 120ω resistor for ct4 the high sensitivity channel.

Burden resistor sizing for openenergymonitor energy monitoring hardware. A good chunk of his write up explains how the used amazon web services aws to process and ultimately display all the data he collects with his esp32 energy monitor. Monitor electricity temperature and humidity. This basic version is for apparent power only.

The esp32 devkitc board works similar to an arduino uno but has more features and superior capabilities. To keep component count low and the circuit as simple as possible the ads1115 is used in differential mode eliminating the need for bias resistors. The two most important components are obviously the esp32 microcontroller and the ct sensor.
