Instructions | Power Analyzer based on a COTS Power Monitoring IC

1

Step 1: Preparation

Order all the parts (Digikey SKUs are in the KiCAD Project)
2

Step 2: Get the schematics and solder the PCB and the teensy with pin headers

Insert the fuse.

Step 3: Build of housing

If you have the BOPLA housing that I used:

1. Take a marker and draw a (35 x 38)cm rectangle. Try to draw it as centered as possible and with a gap of ca. 1.5cm from the bottom of the housing.

2.

Make a cutout for the display.
E.g. with a dremel or by drilling holes and cutting the parts between the them with a side-cutter.

Step 4: Wiring in the housing

Prepare 5 wires. Two with a ring-style crimp-connector and a blade-style crimp connector (for Phase and Neutral IN) and another two with a blade-style crimp connector and a ferrule. Last but not least, a green-yellow wire for passing the ground.

Connect them to the Socket with nuts and washers and to the plug as follows:

Step 5: Connect the PCB to the housing and connect the display
6

Step 6: Fix the display with some double-sided tape to housing from the inside.

Step 7: Clone the repository

Git-Repo and open the project in the Arduino IDE with the Teensyduino Add-on.

Open the project and upload it, using the following settings:

Step 8: Open the GUI
If you have installed python3.9 or greater, you can just run
```
pip install -r requirements.txt
```
and then
```
python3 main.py
