Abstract: The present disclosure provides diaper care system and method. In this method, diaper sensors senses and transmits usage parameters of diapers to a server; when it is determined that one of the diapers needs to be replaced, the server monitors the change in the usage parameter of the corresponding diaper sensor, and determines whether this diaper which needs to be replaced has been replaced or not.

Abstract: The present disclosure provides diaper ordering system and method. In this method, a mobile device executes a mobile app to receive a user setting including a preset diaper quantity; a diaper sensor senses a usage parameter of a diaper, and the mobile device determines whether the diaper is needed to be replaced; if so, the mobile device is based on the preset diaper quantity to calculate a remaining diaper quantity. When the remaining diaper quantity is less than a threshold amount, the mobile app performs a diaper ordering process.

Abstract: The present disclosure provides diaper prediction and correction system and method. This system includes a diaper sensor, a server and a mobile device. The server is configured to store crowdsourcing data including a plurality of sensing criteria corresponding to a plurality of geographic regions, different genders, a plurality of ages, a plurality of diaper data. The mobile device is configured to execute a mobile application to pair with the diaper sensor and to transmit a location information, a wearer's sex and age, and a brand or a model of a diaper to the server, so that the server selects a corresponding sensing criterion from the sensing criteria and returns the corresponding sensing criterion to the mobile device, and the mobile device is based on the corresponding sensing criterion to determine whether a diaper sensing signal from the diaper sensor reflect that the diaper needs to be replaced.
