WIRELESS temperature manage FOR A MICROBREWERY

When brewing your own beer, temperature manage is important. If the temperature isn’t regulated correctly, the yeast will be killed when it’s added to the wort. It’s finest to awesome the wort from boiling down to about 25 C swiftly before adding yeast.

To do this, [Kalle] came up with a wireless temperature controller for his house brewing setup. The gadget utilizes a heat exchanger to awesome the wort. An ATmega88 linked to a H-bridge controls a valve that regulates flow with the warm exchanger. It reads the present temperature from a LM35 temperature sensor as well as actuates the valve to bring the wort to a set point.

A neat addition to the develop is a wireless radio. The nRF24L01 module supplies a wireless link to a computer. There’s an Android application which communicates with the computer, supplying tracking of the temperatures as well as manage over the set point from anywhere [Kalle] can get an Web connection.
