BrewBench is an Arduino brew monitor, controller and alert system for the home brewer enthusiast. It uses the Arduino REST API to interface with thermistors connected to the analog ports. You can also connect a relay to the digital ports and add a heater / pump to create a RIMS system. The software will start/stop the heater/pump based on the target temperature you set.
Setup the Arduino
Wire up sensors and relays
Once you have connected the temp sensors to the analog or digital ports, open the web app and enter the Arduino IP address or hostname in settings. Add a sensor and start brewing.
