Arduino or Raspberry Pi

by simmer65 on Fri Jun 30, 2017 3:11 pm

I have a project and I'm looking for advice on the best path forward. Briefly, I need a device to read a current transformer (CT) to see if the breaker in my process oven has tripped. If the temperature controllers are enabled and there is no current flowing to the heating coils, then I want the oven to send me an email.

I am already familiar with reading the low voltage AC waveforms with an Arduino, but I don't know how to send an email from the Arduino. I'll have to figure out how to connect the Arduino to the wireless network and then how to send the email...either through an SMTP library or a 3rd party service.

The alternative:
I already know how to send an email from a Raspberry Pi, but A/D conversion will have to be done with an added component.

Any feedback about the learning curve for either of these two paths would be greatly appreciated.

If you are already familiar enough with the Pi to send email, adding an ADC would probably be the easiest path for you: https://learn.adafruit.com/raspberry-pi ... 5?view=all

You could go with this digital input switch option if your oven draws some current when it is on. http://www.alliedelec.com/dwyer-instruments-mcs-111050/70673425/

Keith,

That switch is a great idea. Thanks.
