Prinsip Operasi

Adhedhasar prinsip optik. interior nduweni LED kanggo 1 pc, triode panampa fotosensitif kanggo 2pcs; lan sisih liyane nduweni siji iyub-iyub silinder; kaya sing ditampilake ing gambar:

Diagram sirkuit

Kanthi iyub-iyub silinder kanggo njaga LED, lan tabung panampa fotosensitif kanggo ndeteksi RPl-1031 negara saiki.
Nalika RPl-1031 muter menyang negara ditampilake ing ngisor iki, LED dibayangke dening iyub-iyub; lan loro photosensitive nampa triodes ora bisa nampa cahya; padha bakal mati state.output tingkat kurang; loro bandar GPIO loro output tingkat kurang.

Nalika RPl-1031 muter menyang negara sing dituduhake ing ngisor iki, salah siji saka triode fotosensitif dibayangke, cahya sing dipancarake dening LED mung bisa ditampa dening siji liyane; tegese triode fotosensitif ing ndhuwur urip, lan triode fotosensitif ing sisih ngisor mati; banjur loro port GPIO output mungguh output tingkat dhuwur lan tingkat kurang.
Nalika RPl-1031 muter menyang negara ditampilake ing ngisor iki, iyub-iyub ora Shadow diode bakal mencorong, loro triodes photosensitive bisa nampa cahya, banjur kabeh mau bakal on.loro loro bandar GPIO output tingkat dhuwur.

Nalika RPl-1031 muter kanggo negara ditampilake minangka below.this negara salabetipun kanggo gambaran 4 loro GPIO bandar tingkat output bakal inter cahnged.
