Monitoring of Incubator Parameters Using Android Applications

This study aims to monitor parameters such as chamber temperature, skin temperature, humidity, and noise from the incubator to prevent temperatures that are too hot, humidity that is too high or too low, and high noise levels that can damage baby's hearing by utilizing the internet system, so that with this tool medical personnel can monitor parameters on android smartphones. This study uses the ESP32 as the mainboard, the Ds18b20 sensor as the skin sensor, the SHT11 sensor as the chamber temperature and humidity sensor, and the analog sound level meter as the noise sensor of the device. From the test results, the largest error at chamber temperature is 0.97% at 36°C setting. In the noise test results, the largest error is 0.73 % at setting 55 dB. In testing the skin temperature on the incubator, a value that is close to linear is obtained where when the chamber temperature setting on the tool is increased, the value of the skin temperature on the incubator and tool will also increase. On the results of the humidity test at the setting of 32-37°C, the humidity value of the instrument and calibrator is 68-70%. In the data transmission test, the device can be monitored remotely on the android application as long as the device and smartphone are connected to the internet.
