Arduino Energy Monitor

This page and linked pages detailed below document how to build whole house energy monitor that has a display for easy quick access to current energy use information usb datalogging for detailed long term data storage and internet connectivity for online graphing.

Arduino energy monitor.

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. 1x 9v ac ac power adapter 1x 100kohm resistor for step down voltage divider. 1x 100kohm resistor for step down voltage divider. All the calculations are done in the digital domain on an arduino.

The display the display unit. Smart energy monitor based on arduino project tutorial by mohamed maher. This basic version is for apparent power only. All the calculations are done in the digital domain on an arduino.

This project creates a real power energy monitor using a nodemcu module with esp8266 12 and ads1115. Nov 19 2008 08 52 pm. Open source smart energy monitor with some new features like terminal commands readings logger and data plotting. Introducing the openenergymonitor system.

Step one gather components. Step one gather components. The energy monitor can calculate real power apparent power power factor rms voltage rms current. Upload the arduino sketch.

The code is shown in the attached images here is the link to download the energy meter code. Ct sensors interfacing with an arduino. The arduino converts the raw data from its analog input into human readable values then sends them to the serial port monitor. Note that if etching your own board the through hole parts will be a bear to solder.

Wiring up the circuit. The arduino energy monitor. Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started. The arduino energy monitor read 17952 times previous topic next topic.

You can use the eagle files to get a professional board made or you can email me and see if i have any on hand for sale. Pre assembled open hardware electricity temperature and humidity monitoring units based on the arduino and raspberry pi platforms. The energy monitor can calculate real power apparent power power factor rms voltage rms current. The sketch is the software that runs on the arduino.

First a quick look at the installed setup. Attached to this step are the eagle schematics and board layouts for the arduino energy monitor shield as well as pdfs for printing and using the toner method for etching your own pcb.
