i'm starting a new project for my home automation, using an arduino.
The plenty of Modules / shields / boards / apps developped by smart people around the world, is truly astonishing!!!
As an electricity technician, in france, dealing with material using 12 to tousands of volts, i know that sometimes we need some interfaces.
and there is the point of my topic :
Many variants of OUTPUT boards are available... from a tiny optocoupler micro board, to a massive 16 relays for high voltage/ load applications...
But I can't find ANY INPUT board in the same voltage rating.
I mean a board able to manage a 110vac or 230vac grid voltage as input and create a 5vcc / 3.3vcc compliant with the arduino products.
it's even hard to find a DIY design on the net...
Is any of you working on such a kind of board ? maybe needing an outside look, by a electric and not electronic tech ?
Lets talk about it
