Nowadays, there are many researches about automatic controlling system of hydroponic temperature. The two most well-known controller systems are PID Controller and Fuzzy Logic Controller. This study discusses and compares the performance of these two main controller systems to control the room temperature of a wick-based hydroponic system for cherry tomato cultivation. In this comparison system, we use an SHT11 module as the sensor and an air conditioner as the actuator. From the test result, PID controller has 2.2 times longer rise time, whereas Fuzzy controller yields 25.3 times larger overshoot in day time measurement.
