Inpatient admission is where the mother and newborn are not separated but are placed in the postpartum care room together 24 hours a day. The presence of joining makes nurses not stay in the postpartum room for 24 hours, thus delaying the handling of nurses when the baby cries. The delay in handling has an impact on the baby's health, according to dr. Hari Martono SpA from RSPI-Pondok Indah, crying babies should not be allowed because it will cause Breath-Holding Spell. The purpose of this study was to monitor in real-time the results of a baby crying using the KY-307 sound sensor and using the NodeMCU ESP 8266 microcontroller. The test was carried out using several sound samples (the sound of a baby's cry, the sound of people chatting, the sound of a dog, the sound of a cat, and the sound of a chicken). Tests have been carried out with samples of the baby's crying sound 30 times at a distance of 3cm – 15 cm in the room. The results of the test show that the tool is able to distinguish the sound of a baby's cry and not a baby's cry. The technique of distinguishing sounds is processed based on the number of waves and wavelengths. The test results obtained the fact that the tool has an error value of 40% and an accuracy value of 60%. In addition to the fact that the KY-037 sensor's the best ability to capture sound waves in the range of 5 -10 cm.
