描述
Grove Tilt Switch 傾斜開關
Grove-Tilt Switch相當於一個開關,用作數字輸入。在傾斜開關內部是一對滾珠,當殼體向上直立時滾珠與引腳接觸。當殼體翻轉向下時滾珠不接觸,因此斷開連接。與滾珠接觸的引腳連接到SIG線,NC表示不連接,在該傳感器上沒有用到這個引腳。
Grove Tilt Switch 傾斜開關的SIG引腳正常輸出低。當傾斜開關向上直立時,傾斜開關內的一對滾珠將與引腳接觸,SIG引腳將輸出高電平。
Grove Tilt Switch
The tilt-switch twig is the equivalent of a button, and is used as a digital input. When the switch is level it is open, and when tilted, the switch closes. It is wired to the SIG line, NC is not used on this twig. There’s a surface-mount resistor .
