What you’ll need:
- Current Transformers (depending on your application)
- SCT-006 20A/25mA micro CT (6mm opening – 3.5mm connectors) – these are great if you have a lot of 15A circuits that you want to monitor
- SCT-010 80A/26.6mA mini CT (10mm opening – 3.5mm connectors)
- SCT-013-000 100A/50mA (13mm opening – 3.5mm connectors)
- SCT-016 120A/40mA (16mm opening – 3.5mm connectors) – for monitoring mains
- Others can also be used as long as they’re rated for the amount of power that you are wanting to measure, and have a current output no more than 720mV.
- AC Transformer: Jameco Reliapro 9v or 12v. The positive pin must be 2.5mm (some are 2.1)
- ESP32 (choose one):
- A 3d printed case (optional)
- Software (choose one):
