reaktor

Once a while I wrote about our project to brew beer. reaktor is the technical part of our Beerberry-project and our way to brew beer with an Arduino and Raspberry Pi.

reaktor itself is nothing more than a DYI-boiler for 20-30 L of beer and a highly sophisticated thermostat-solution implemented via an Arduino and Raspbeery Pi.

reaktor_zentrale is reaktor’s central human interface to control the whole brewing process. Current implementation is done in a jBoss-container running on a Raspberry Pi. reaktor_zentrale is receiving continous sensor-values and decides whether reaktor should heat its mash or not. Configuration and logging is been done via local MySQL-database so that the whole brewing process can be analyzed further.
Check out my reaktor_zentrale on GitHub to get the code.

reaktor_schaltwerk is an Arduino-patch running currently on an Arduino Uno micro-controler. Connected to the Arduino, two PT1000 temperature-sensors are used to monitor the current mash-temperature. A hacked Intertechno-remote control sends on/off commands to two plug sockets to switch two circuits of a heating element. Its main loop is designed to fetch values of two connected PT1000-temperature sensors and displays them via serial-console. Feebdack is been processed from reaktor_zentrale.

  1. Hello André,

    I found your website when searching the internet for an easy way to interface a PT1000 temperature sensor to an Arduino.
    I would like to ask you how do you interface the leads on the PT1000 sensor to the Arduino. Do you connect the PT1000 directly to the Arduino or there is anything between Arduino and PT1000?
    Can you plese point me to a schematic?
    Thank you very much for any help.

  2. Hi Miguel & Thanks for your interest!
    We attached the PT100 to the Arduino directly. The last couple of days I was thinking of drawing some additional schema but it is as simple as it is 😉

    Let me know once you’ve build something with the Arduino and the sensors!

    Yours,
    André
