small (IoT device) 3-phase wattmeter
$750-1500 USD
Pagado a la entrega
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.
