Baby Incubator Temperature Control With PID System

A Baby incubator is one of the right instruments to overcome problems in handling newborn babies. An important parameter to control is the temperature of the baby incubator room. A study has been conducted on the Design of Baby Incubator Temperature Control with a PID System using a DHT22 sensor for the incubator room temperature sensor and a DS18B20 sensor for the baby's skin sensor. The microcontroller used is ATmega328. The temperature is maintained at 36 °C.  There is a heater component to heat the Baby Incubator if the temperature is >36 °C, a blower as a cooler if the temperature is <36 °C.  The temperature condition is displayed on the Nextion 4.3" LCD in real time using touchscreen technology. After being compared with the Incubator Analyzer, the overshoot value on the Incubator Analyzer was 0.74% while on the device made it was 0.20%. While the error value on the Incubator Analyzer was 0.02%, on the device made it was 0.01%. So it can be concluded that the tool operates properly according to what was planed.
