Design of Baby Incubator Equipped with PID Temperature Controller and Body Weight Sensor

This study added weight parameters to monitor the baby's weight development and a PID control system to maintain the temperature value at the set point. This study aims to develop a temperature control PID system in the baby incubator so that the chamber temperature can be stable and a weight sensor to monitor the baby's weight development. This study uses the Arduino Mega Pro 2560 as the mainboard, the Ds18b20 sensor as the skin and chamber sensor, and the loadcell sensor as the weight sensor. Based on the test results on the chamber temperature parameter, the highest error value was at chamber temperature of 0.62% at 32 °C. The highest overshoot value at room temperature was 0.93% at 32 ºC. In the skin temperature parameter, the highest error value was 0.26% at 36 °C, and in the skin sensor test, an error of 0.06% was obtained. Then in the weight parameter test, the largest error value was found at 1 kg with an error value of 4%. From the data obtained, it can be seen that the baby incubator, with the development of the PID temperature control system and body weight sensor, has worked quite well because the error value of each parameter is still within the tolerance value limit.
