Compact case for PZEM-004T with Arduino Script

Here's a compact case for PZEM-004T V3 0-100A 80-260V. It consists of two parts which slot together and are then screwed together.

You can buy the case and other needed items on AliExpress:

PZEM-004T 0-100A 80-260V

2.6*6 PB Stainless steel pan screw for plastic

In the downloads, you'll also find an Arduino script.

I use this app to record and save current data on my phone:
USB Serial Console App
