Sfat pentru alegerea componentelor

Recommended Posts

Guest cercelaru

Va rog sa-mi ziceti si mie ce diode in IR sa aleg pentru o bariera in IR.Am nevoie de o dioda emitator si una receptor. Mersi mult.Daca se poate cu tranzistoare in IR nu le refuz. Numai sa-mi zice-ti ceva ce se gaseste mai usor pe aici pe la noi(in Romania).

Bariera in IR? :smt025Mai multe detalii despre aplicatie.Se pot folosi optocuploare in capsula de 2x4 pini , optocuploare cu fantasau componente separate.Pentru componente separate se pot folosi piese recuperate de latelecomenzi si receptoarele din TV.Asta doar pentru diode de emisie si receptie.Sunt de asemenea module alimentate la 5v, receptia folosita la TV sauaparate video, foarte compacte ( dimensiuni 1x1x1 cm) care se gasescca piese de schimb.Avantajul este ca iesirea este "digitala" si se potlega direct la un microprocesor. :director:
