senzor hc sr501


Recommended Posts

Am acest senzor de miscare, pe care am vrut sa-l fac sa-mi comande un kit cu releu cu un canal construit cu un tz pnp rezist polarizare si doua leduri de confirmare a starii modulului. Senzorul are iesirea nivelului logic pe 3,3v iar releul poate fi comandat cu 5v.Ce modificari s-ar impune acestui modul sau ce montaj trebuie re4alizat ptr.ca sa-l adaptez senzorului?

Cred ca s-a rezolvat problema.Am inlocuit tz-ul cu un npn ,dioda pe bobina releului,si ledurile de semnalizare si automat schimbarea polaritatii alimentarii. Scema acestui modul cu releu nu am gasit-o ,dar m-am ajutat de scheme asemanatoare cu acest tip de tz(npn).
