DESIGN OF MONITORING TOOL FOR BABY WHILE SLEEPING BASED ON INTERNET OF THINGS USING NODEMCU ESP8266

Abstract

During sleep, the baby's body produces three times more growth hormone than when the baby is awake. Because the baby's brain growth reaches its peak during sleep, deep sleep is very important for its growth. This monitoring tool monitors sleeping babies by utilizing load cell sensors to detect the presence of babies and sound sensors to detect baby cries, NodeMCU ESP8266 as the control center, and the Blynk IoT platform as a user interface connected to the internet. Design of monitoring tool for baby while sleeping based on internet of things using NodeMCU ESP8266 has been completed and can work well to monitor the presence of babies and detect baby cries. Load cell sensors can calculate the baby's weight of 0–20 kg. When the detected baby's weight is lower than (<) 2 kg, the device will send a notification "BABY IS NOT IN PLACE." When the detected weight is higher than (>) 2 kg, then the device will send a notification "BABY’S SLEEPING.” The sound sensor can detect sound sources with a distance of 0–50 cm. When the sound sources are 0–50 cm away, the tool will notify “BABY’S CRYING.” When the sound source's distance is higher than (>) 50 cm, the sound will not be detected, and the device does not send any notification to the Blynk application
