This paper presents a module for monitoring the grape fermentation process constructed of low cost sensors for temperature, wine acidity (pH), alcohol and carbon dioxide released gases. Sensor values are recorded over the wine fermentation process and are sent through wireless modules in real time to a server. Constituent part of the module is a microcontroller PIC16F877A. It processes data received from sensors and sends them to the server through Ethernet controller ENC28J60. The main advantage of this low cost prototype is the possibility to be used by small winemakers for control and monitoring of a grape fermentation process. The proposed system has been tested in a winery in the Tikves region and it fulfilled the initial expectations.
