nafikiria kutengeneza kifaa kitakachoweza kuzima gari remotely kwa ajili ya ulinzi ila project yangu nahisi nitafanikiwa kwani mimi ni fundi mzuri wa umeme wa magari, vitu nitakavyotumia ni kama simu na ECM (control box ya gari) issue ni kwamba nahitaji kifaa cha cha kubadilisha 3volt dc to 12volt dc ili niweze ku switch 12v0lt reley.

Ama tumia a mechanical relay switch with 3v input to close the 12v relay circuit au tumia npn transistor as a simply relay switch- connect one end of relay to 12v power supply and the other terminal to collector of transistor. Connect your 3v to transistor base via a high resistor ,earth the emmiter .

mkuu namashaka na ww sana na huo ufundi wako wa umeme wa magari hivi kweli kabisaaa swali hili ndio limesimamisha project yako??

sababu mambo uliyofikilia na unayotaka kuyafanya nimakubwa sana hili sio swala la kukukwamisha hata chembe.

hiyo npn transistor naweza pata wapi au katika kifaa gani

Jindal Singh · Sep 22, 2015

hapana hii issue ni siliazi caz nilishawahi kujalibu ishu moja ya kuweka kifaa cha ulinzi home kwa kutumia simu mbovu pindi mtu atakapoingia ndani kwa kutumia mlango basi my phone itaanzakuita nikiwa mbali ila mi sijasomeaga darasani ila ni utundu tu wa akili.

iyo ya kununua itakuwa issue sana kwangu labda kwa hapa dsm

unaweza tumia NPN transitor au MOSFET na base transitor 3 -10k ili kuweza kuswich relay 12 volt

.kuwa makini usije ukaswitch stater ya gari kwa relay zenye uwezo mdogo chini ya 200A

tupia photo ya hiyo kitu
