摘要：
Diapers rash are harmful to the babies and the elderly; so, wetness detection technologies have been sophisticated by many research worker to assist in discovering these events. The study and survey offered here looked into a radio frequency-based microcontroller and GSM for wetness detection. One of the crucial concerns is not only the detection of humidity but the Health complications of diapers rash. This study utilizes a wetness detection system with different types of alarms: audio buzz, flashing light emitting diode, and Smartphone. Our proposed system consists of a wetness sensor, microcontroller, radio frequency transceiver microcontroller, and GSM modem, or computer. Two thin wires between diaper sheets or layers of medical dressing set up the wetness sensor. The two or four thin wires connect to a couple of pressing studs sticking out from one end of the diaper or gauze. When the wires are wetted, the resistance between the studs falls down a pre-established threshold, launching the alarm. Radio Frequency transceiver passes the warning alarm through Microcontroller to the GSM modem. Consequently, Smartphone and other devices forward the alarm to whom it may concern wetness or bleeding is occurring.
