When roasting coffee, I like to know and remember what the ambient conditions are, so I can later compare roast profiles and bean behaviour over different seasons.
Until recently I used a "Eve" device from Elgato and its app on my iPhone:
|Eve Degree device, by Elgato|
|Data from Eve degree, showing room temp, moisture, pressure|
Now, Marko has further expanded Artisan to read these data fully automatical, at startup, from Phidget modules.
To get this up and running, Marko sent me this shopping list:
- a Phidget VINT HUB (https://www.phidgets.com/?tier=3&catid=2&pcid=1&prodid=643)
- a Phidget VINT HUM1000 (https://www.phidgets.com/?tier=3&catid=14&pcid=12&prodid=644)
- a Phidget VINT PRE1000 (https://www.phidgets.com/?tier=3&catid=64&pcid=57&prodid=719)
- and 2x VINT cables (as suggested on the order pages of the HUM1000 and PRE1000 modules)
Plus download and install the Phidgets v2.2 driver for Mac OS X from their pages.
I expected some trouble in assembly, or at least in configuration, attempting to actually make the Phidgets talk to the laptop and Artisan, but it turned out to be dead simple, a matter of unpacking, clicking in, connecting, and starting.
Artisan now requests, at START, the ambient values from the Phidget sensors. So it's a good idea to make sure the Phidgets hub is connected to your computer before clicking START in Artisan. One can also update/refresh the ambient data at a later time in the Roast Properties menu.
