Hol | Hol troubleshooting his electronically controlled mash keggle at the Microcircuits Hack Night. DS18B20 sensors and a sainsmart 4x relay board extend the reach of the vanilla-flavored Arduino Duemilanove. Temperature is controlled to within 0.5F and plotted in processing. This is a bang'bang type controller, switching an AC pump and a 1000W resistive heating element on at (Tset - 0.5F) and off at (Tset + 0.5F). Upon looking at the temperature curve from room temperature up to 100 degrees, it appears 1000W is not enough power input to command the system. A second 1000W element will be added prior to the first brew. | ||
