    지난번에 mobile 접속을 안내하여 주셔서 다시 감사드립니다.
    접속 할 때 마다 고마움을 느낍니다.
    노드레드 DHT11 pin numbering에 대하여 질문드립니다.
    BCM GPIO, Physcical pins(rev 1), Physcical pins(rev 2), WiringPi(rev 1), WiringPi(rev 2)가 있는데
    이강좌에는 WiringPi(rev 2) pin number 4번을 선택하셨는데..... map을 살펴 보니까 BCM 18, pin 16, WiringPi 4로 된것 같은 데...
    왜 이렇게 복잡한 pin-number체계를 가지고 갈까요.?
    WiringPi 는 node.js에서 C로 coding 하기 위한 것 같기도 하고... 그렇다면 이 강좌에서 WiringPi(rev 2)를 선택 한것은 DHT11의 C 라이브러리를 호출하기 위한 것인가요.
    아! 너무 헷 갈려요

    I am installing it on raspberry pi but it is not working. I followed all the steps. But on the last step dht node does not install.

      I faced similar issues couple of days ago. In order for successfully installation of DHT11 we have to install some pre-requisite files. You can easily get those files from internet
