Design of Baby Incubator with Humidity Parameter and Blue Light Theraphy

The baby incubator has a humidity parameter to maintain body humidity in premature babies. However, the circulation of moist air in the chamber by manually opening and closing the valve may cause bacteria to enter the chamber and can disturb the peace of the baby. In addition, premature babies with low birth weight (LBV) are more often affected by jaundice, so intensive therapy and care are needed in a baby incubator. In this study, a baby incubator was designed with humidity parameters and Bluelight Therapy which uses the SHT11 sensor to detect humidity in the chamber and maintain humidity in the range of 50-70% RH. Based on the measurement data, the largest error value is found at 34°C of 0.53% RH. Bluelight Therapy uses 4 TL lamps arranged in parallel with an hour meter. There are 3 timer options for bilirubin therapy, 1 hour, 2 hours, and 3 hours. Radiation testing on the lamp was carried out on the right, center, and left of the baby mattress using a Phototherapy Radiometer measuring instrument. The measurement data shows that the largest radiation value is in the middle of $641 \mu \mathrm{V}/\mathrm{Cm}^{2}$. So it can be concluded that the humidity measurement is still at the humidity tolerance limit of ±3.5% RH, and the radiation measurements on the lamp indicate that the lamp is suitable for therapy because it has a radiation value of >$400 \mu \mathrm{W}/\mathrm{Cm}^{2}$.
