안녕하세요 임진환입니다. 메일 mpmedical1985@gmail.com

팀원은 임진환 장희은 입니다.

저희팀은 온도센서를 활용한 체온체크 웨어러블 기기을 제작하려고 합니다.

 

아두이노에 온도센서를 연결하고 각부분의 온도를 LCD모니터에 나타내고, 네오픽셀을 활용한 색상으로 체크하고 일정온도이상 올라가면 경고음과 온도를 낮추는 기능을 구현하려고 합니다.

 

사용할 센서는 DS18B20을 사용하여 여러 개의 온도센서를 하나의 와이어를 통해 준비할 계획이며, 준비물은 다음과 같습니다. 

 

준비물

1. DS18B20 온도센서 10개(10cm당 1개씩 연결하여 총 길이 100cm(조끼둘레))

2. 조끼

3. 5V 건전지

4. 아두이노

5. 버저(경고음 발생)

6. 네오픽셀 디스플레이 (10개, 온도센서 하나당 네오픽셀 한개씩)

7.태양광페널
