arduino mkr1000 wifi with a Solid State Relay?
Sep 19, 2020, 02:06 am
I would like to drive a single channel solid state relay capable of handling 120vac @<1amp as directly as possible from a mkr1000.
Small size matters greatly. Switching speed does not matter at all as the switching frequency will be less than 1 hz.
The relay will trigger as many as 3000 times per day and will need to operate for many years so it must be a SSR.
This application will pull a 120vac (low current) control signal to low for 1 second intervals based on the wifi and programmatic responses.
Can the mkr1000 WIFI drive any SSRs? Is there a better option that is the same size as the mkr1000?
There is a 5vcc available however size is very restricted.
Thank you

Can your mkr1000 light a LED? That is all it takes for a SSR.

That depends on the LED does it not?
And I do not have one yet, I will not buy my prototype Arduino until I can figure out which components are the best suited.
And which SSR? I need one that is very small and can work with the mkr1000 (or similar).

Even a small Omron G3MB-202P SSR needs the same or a bit more current than a 3.3volt pin can provide.
Common
SSR boards
solve that with a
transistor between pin and SSR LED
.

Random thought but would a
level shifter
be suitable for running an SSR ?
They can be had in very small module sizes maybe enough to glue to the side of an SSR.
Many of the Chinese modules also claim to run from 3 volts too.
It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

How about this SSR instead, if you can live with just 825mA of switching current:

Can the MKR1000 drive 5mA?
Datasheet for the chip would suggest that at least some of the IOs can sink up to 10mA.

@ballscrewbob
That is also a great idea, I'll try that too!
Thanks!
