(* Studies conducted simultaneously with a full time job) Thesis: Automatic Control System for Industrial Cold Storage. The system designed included the Software interface for control and collection of statistics, as well as Hardware specifically tailored for cooling control. The hardware was developed with PIC micro controllers and additional discrete components while software was written in C/C++ languages.
