Arduino Energy Monitor

The sketch is the software that runs on the arduino.

Arduino energy monitor.

All the calculations are done in the digital domain on an arduino. 1x 9v ac ac power adapter. The arduino energy monitor read 17952 times previous topic next topic. 1x 100kohm resistor for step down voltage divider.

1x 9v ac ac power adapter 1x 100kohm resistor for step down voltage divider. 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. Step one gather components. 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.

Note that if etching your own board the through hole parts will be a bear to solder. Pre assembled open hardware electricity temperature and humidity monitoring units based on the arduino and raspberry pi platforms. This basic version is for apparent power only. This project creates a real power energy monitor using a nodemcu module with esp8266 12 and ads1115.

The arduino energy monitor. Open source smart energy monitor with some new features like terminal commands readings logger and data plotting. Ct sensors interfacing with an arduino. The display the display unit.

Nov 19 2008 08 52 pm. Smart energy monitor based on arduino project tutorial by mohamed maher. The energy monitor can calculate real power apparent power power factor rms voltage rms current. Wiring up the circuit.

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. The energy monitor can calculate real power apparent power power factor rms voltage rms current. Assemble the components per the diagram above. Because your setup ct resistors and input voltage may be different there is a scaling factor in the sketch which you will need to change before you will get.

All the calculations are done in the digital domain on an arduino. The arduino converts the raw data from its analog input into human readable values then sends them to the serial port monitor. First a quick look at the installed setup. Introducing the openenergymonitor system.

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 code is shown in the attached images here is the link to download the energy meter code.
