Ventilator cu timer

Buna ziua. Stiu ca exista ventilatoare in comert care dupa stingerea luminii(fir de faza) mai functioneaza x timp. Am firele trase, am deja ventilatorul si vroiam sa il fac mai inteligent.

 

Ce montaj pe baza de triac si o constanta RC as putea face? Idei? Vreo schema?

Ma gandesc ca montajul trebuie sa fie in primul rand compact si ieftin. Am gasit pe net ceva cu uC, dar mi se pare ca e o solutie destul de complicata. http://arv.radioliga.com/content/view/218/44/

 

Protectia la umezeala, am deja rezolvarea pt ea.

Daca ai doar faza si nul trase acolo si se cupleaza/decupleaza odata cu becul nu prea ai ce face. Mai trebuie un fir de faza permanenta. Ca sa il faci mai destept iti iei o priza programabila si ii spui sa mai mearga de capul lui din cand in cand cate x minute.

Asa se poate face un delay si cu lm555. Mai puneti in circuit o sursa pt alimentarea modulului, poate fi si un incarcator de telefon. Spatiu sa aveti. Puneti totul intr-o doza cu IP mare.
