Hi
Yes - the “host” in a Phidgets setup has its own power supply.
The only hurdle with iPad, is that data must be sent wirelessly. It's a pro and con at the same time. So, a Phidgets Temperature Sensor needs a means of broadcasting the data it measures from the probe - this is the “host”.
The host runs the Phidgets Web Sevice to send this data over Ethernet via a WiFi network (internet service is optional).
A host can be either A) a Laptop running the Phidgets software, or B) The Phidgets SBC with a WiFi adapter.
Both of those host options have their own power supply, so it should be a simple matter of plugging the USB cable from the Phidget Temperature Sensor on the roaster to whichever “Host” you want to use.
I don’t “think” Diedrich includes an SBC in their Phidgets setup - the assumption being that you will be hardwiring the cataloging software via USB. If not, you’ll need to use a laptop or order an SBC.
I like the SBC, because it’s simple to install - just plug it in and forget about it. Plus, it’s possible to run many different temp sensors off of one SBC, in case you get more roasters.
But, it’s also easy to just hook a laptop up the for time being, to test the setup. Then proceed with an SBC later.
Hope this helps. Let me know of any other questions.
Kind regards,
Danny Hall
