The most important factors that affect the output of mushroom productivity is temperature. From that, this paper presents the design and simulation of an Automatic Control Room Heater system for Agricultural industry. This system allows the user to set a desired temperature for control room and fruiting phase which has been set between 34 °C - 32 °C and 28 °C - 32 °C, respectively. The process was developed by the responds of the system by turning ON any of loads (fan or a heater) automatically depending on the temperature difference. The system was designed and simulated using solid works and Arduino software, respectively. As a result, the planted mushroom that used automated handling method was advantageous in morphology features compared with manual handling method. In addition, the total yield of mushroom for automated was higher than manual handling.
