Goo9: A wireless sensor network system for wet diaper detection

The Goo9 system is composed of a detection sensor module (include a humidity sensor and a temperature sensor), a data processing module, a cloud-based database, and a baby profile module. The humidity sensor and temperature sensor detects the temperature/humidity changes of a diaper and transfer the data of diaper change to the data processing module for analysis. The analysis results about the wetness levels of the diaper (dry, slightly wet, wet and very wet) are represented by four emoticons (happy, mild, uncomfortable and crying). Based on the analysis results, the Goo9 system sends the corresponding emoticons, temperature/humidity numbers and diaper change reminders to the Android or iOS mobile phones of baby caretakers. In addition, baby caretakers can provide their feedback about whether or not the reminders are too early, too late or timely so that the system can learn, improve and provide more precise and customized diaper change reminders.
