Leaving a babies/children diapers in a wet condition in long times will cause rash/irritation or other skin diseases. Sometimes, in babies/children care centre, the childcare workers cannot change the diapers often because they will not be noticed that the children diapers already wet. In this paper an online monitoring system for display the condition of the babies/children diapers condition in childcare center is presented. The Wi-Fi module is applied for communication system between the display system and the diaper sensors system. The DHT22 sensor is used for detecting the dampness of the diapers and also for sense the temperature and humidity in and around the diapers, while the sound sensor is used to detect the sound of baby crying. The monitoring system of the device develop able to display more than one diaper condition. The display system used the Blynk application on the user’s smart phone.
