Abstract

This paper is about a smart pillow, and a smart diaper. The smart pillow analyzes the frequency of a baby's cry and applies its digital value to the band pass filter. If the crying is between 300-600Hz, the white noise comes out. The smart diaper alerts to the smart phone if the humidity outside the diaper is over 99%, or the temperature is over $29^{\circ}C$ after the defecation of the baby. The smart diaper also prevents choking of the baby by alert to smart phone if they are in a dangerous position by sensing the location of the infant.

본 논문은 스마트 베개와 스마트 기저귀에 관한 것이다. 스마트 베개는 아기 울음소리의 주파수를 분석하여 나온 디지털 값을 대역 통과 필터에 적용한다. 만약 300-600Hz 사이라면 백색 소음을 출력한다. 스마트 기저귀는 아기가 배변 시 기저귀 외부의 온도가 $29^{\circ}C$이상, 습도가 99% 이상일 경우에 스마트폰에 경고 알람을 울린다. 또한 스마트 기저귀는 아기가 누워있는 위치를 감지하여 뒤집혔을 시 스마트폰에 경고 알람을 울려 아기의 질식사를 예방한다.
