Monitoring is a continuous activity to monitoring the patient's condition to facilitate medical personnel in monitoring the performance of the incubator, and early detection of problems experienced. This study purpose to design a tool for monitoring room temperature and noise for baby incubators with an Android display. To measure the temperature and noise used the sensor LM35 sensor as a temperature sensor and Analog Sound Level Meter as a noise sensor, the monitoring process use the esp8266 module to send data from hardware to android and controlled by Node-MCU. From the research, the error value of temperature and noise readings is below ± 1.5%. The biggest error value of temperature reading in the measurement of 34oC, which is 1.09% and the smallest error value at 36 oC, which is 0.04%. Whereas the noise reading was the biggest error value at 80 dB measurement which was 0.70% and the smallest error value at 50 dB was 0.16%.
