BrewBench is an Arduino brew monitor, controller and alert system for the homebrewers and pro brewers. 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 on fermenters with a thermowell.

BrewBench works with many popular sensors, controllers, and Arduino boards.

Sensor Thermistors Temperature
Sensor DS18B20 Temperature
Sensor PT100 Temperature
Sensor DHT11 Temperature / Humidity
Sensor DHT12 Temperature / Humidity
Sensor DHT22 Temperature / Humidity
