Temperature Stability and Humidity on Infant Incubator Based on Fuzzy Logic Control

Premature babies were born need to be placed inside an incubator to keep its body temperature and humidity in a certain condition. In this paper shows the design and implementation of baby incubator using intelligent control to keep the temperature and humidity. The particular incubator uses an Arduino Mega 2560, an Arduino Uno, an DHT22 Sensor, and an LM35 Sensor. Fuzzy Logic Control has implemented inside the Arduino Mega 2560 to keep the maximum overshoot oscillations and to keep the error signal under 5%. The desired temperature is around 36 degrees C and the humidity around 80% to 60% RH value. The research is conducted in two sessions, one without a load and one with 2 Kg load to simulate the weight of a Baby. The testing result of incubator without load has achieved the stability level which it is quicker than with 2 kg load. Overall the maximum overshoot and the signal error on both research accomplished with the set goal is under 5%.
