Follow up! Arduino-based dual-stage temperature controller for beer brewing (photos). Mike writes…
Just got done brewing!
Here are a few more pictures.
The TMP36 sensor leads were isolated with electrical tape, then heat shrinked and sealed with black RTV silicone for moisture resistance.
The carboy sensor is taped to the side of the carboy and insulated with bubble wrap. The Arduino code takes precautions against condenser short-cycles and temperature overshoots.
This is my first all-grain brew since 2007, and I’m happy to get back into the hobby with parts from Adafruit!
