BrewBench is an Arduino brew monitor, controller and alert system for the home brewer enthusiast. It uses the Arduino REST API to interface with temp sensors.


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.


BrewBench Monitor can easily be used with fermenters with a thermowell.
