Description

I want to develop a small (IoT device) 3-phase wattmeter that measures:

* V

* I

* P (active, reactive, ...)

* phase angle

* no LCD

* no buttons

* RS-485 interface

* programmable to utilize the RS-485

* powered by the mains

* GSM module

* pulse for active and reactive power

* small size (10x10x3cm)

* AC 3-p 4-w

* 120v and 230v

* CT current 5A(6A)

* programmable CT ratio

The development includes schematic, BOM, Gerber files, source-code, .... etc

Must be READY and Build-to-Print.
