WIRELESS WET DIAPER ALARM AND CORRESPONDING DISPOSABLE DIAPER PRODUCT OF THE ALARM

摘要

Disclosed is a wireless wet diaper alarm comprising a passive RFID tag (2), an RFID reader, and an alarm system, with the RFID reader emitting a signal to the passive RFID tag (2) and reading the information sent back from a disposable diaper product (1), wherein the RFID reader reads and analyzes data, and when the humidity is greater than a certain limit, the RFID reader triggers the alarm system. There is/are N passive RFID tag(s) (2), wherein N is a positive integer; and the RFID reader is set to read the passive RFID tag (2) when the humidity is greater or lower than a certain level. Also provided is the disposable diaper product (1) comprising the above-mentioned wireless wet diaper alarm. Since the passive RFID tag (2) is added to the disposable diaper product (1), the passive RFID tag (2) will be affected by the humidity of the surrounding environment and then a parameter, such as impedance thereof, will change, causing the data read by the RFID reader to change, so it is inferred that the wet diaper state of the disposable diaper product (1) is wet.
