Hi,
newbie to electronics so please pardon me for my tardedness.... Quick question though, I was desigining a home security system with some reed switches and was wondering whether there is a guideline as to which voltage I should use (24V, 12V, or 5V.) I know that using a lower voltage such as 5V is probably not a good idea because the wire resistance for longer length of wires might cause problems.
Is there any guideline for which voltage levels should be used for which type of application (I know industrial applications mainly use 24V, how about for home??) Or is there a guideline for what voltage you should use depending on the length of the wiring and amount of electromagnetic interference?
Would appreciate any help!!
Thanks!!
