Assemble the components per the diagram above.
Arduino energy monitor calibration.
I want to add a second ct input and am struggling with the code.
Upload the arduino sketch.
For a more precise calibration continue with this steps.
The code is shown in the attached images here is the link to download the energy meter code.
Now you can upload your sketch onto your arduino if you haven t uploaded a sketch before then follow this guide on getting started.
This is awesome project for me and i have it working well with one current input sensor and one ac mains input.
All the calculations are done in the digital domain on an arduino.
Step one gather components.
The arduino converts the raw data from its analog input into human readable values then sends them to the serial port monitor.
Check these measures whit the values reported by the energy data logger thru serial monitor.
An energy management system can help monitor control and reduce the energy consumption significantly.
I am building it off the how to build an arduino energy monitor measuring mains voltage and current.
Iron electric heater etc measure vac at the input of the device.
I am building a multi input energy and cycle monitor.
Connect the energy data logger on a resistive load around 2000w i e.
You can measure all electrical parameters for utility input and do the same for renewable source like solar or wind turbine at the same time.
We built our source code to handle up to 5 inputs measuring and 5 out measuring you just need to add more cts and pts for each additional input outputs as we will discuss that in hardware section.
Measure the current consumption of the device.
The sketch is the software that runs on the arduino.
So you can monitor the parameters as well as calibrate and modify different settings from your smartphone via ota.
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.
The calculated power and energy by the arduino wemos is displayed on a 0 96 oled display module.
The inbuilt wifi chip of the wemos is connected to the home router and linked to the blynk app.
Statistics reveal that the energy monitoring and managing systems can reduce energy costs from 8 up to 20 which is a big deal.
Above all being able to monitor it from a phone makes it much more convenient.
