모니터링을 위한 무선 센서 시스템


출처 : Designing a Wireless Sensor System for Storage Monitoring



-. 창고 및 냉장 시스템의 온도, 습도, 문 개폐를 감지 및 모니터링
-. Redpine Signals 의 802.11n모듈을 사용
-. 온, 습도를 위한 센서는 Sensirion의 SHT75를 사용 (I2C 인터페이스)

-. 문개폐의 감지는 I/O를 이용
-.Zigbee나 Bluetooth에 비해 Wi-Fi 솔루션이 좋은 이유는 이미 네트워크 인프라가 깔려 있기 때문
-. 전력소모면에서 TCP 보다는 UDP 가 유리, 왜냐면 TCP의 경우 접속을 해야 하므로 ON 되는 시간이 길다.

mil 단위

PCB를 설계시 사용하는 OrCAD 같은 프로그램에서는 부품의 단위로 mil 단위가 기본으로 설정이 되어 있습니다.


그리고 칩 저항 같은 SMD 부품도 mil 단위와 mm 단위를 사용하여 부품의 치수를 얘기합니다.


1000mil 1 Inch(25.4 mm)이며, 100mil 2.54mm, 즉 브레드 보드의 핀 피치로 기억을 하고 있으면 편합니다.


칩 저항같은 부품은 다음과 같이 통칭합니다
