I am looking at automation of my brewery sometime in the future. Until then, I am thinking of adding an electronic temperature sensor. While poking around for something that senses temp with upgrade potential this just was brought to my attention:
4 relays and 6 inputs (digital (I/O), analog or temperature) on one board for $60.
No software however. Just wondering if any of our Brewtroller types thinks this might be an interesting way to run a few pumps, etc.
