How is best method to protect outdoor signal from lightning ?
Signal and control cable is use to control smart home security sensor; LDR sensor, flame sensor, PIR sensor, also control 5v Relay, 12v DC Solenoid valve , etc
I use CAT5e wire for this wire, can I use ethernet surge protector to protect that signal and control cable from lightning risk ?, is that good idea ?, can ethernet surge protector interference sensor signal (some is PWM) ?, and do you think that ethernet surge protector can change voltage inside signal wire ?
also how to protect 5v 16channel arduino relay from voltage spikes ?, let's say if relay get failed, and 220v come into 5v control cable, it can damage micro-controller, power supply, and another stuff than connected both directly and indirectly, can I use ethernet surge protector to protect 220v enter 5v DC wire ? I think that stuff is only protect from more than 1kV voltage spike, another good way ?, MOV ? GDT ? TVS ?
