1-Wire Surge Protection
After reading several articles, I decided to install a surge protector circuit to protect the 1 wire weather station
lightning strikes can cause a large magnetic field this can play havoc with the electronic devices
and may even damage than
The surge protection circuit is from Philip Gladstone Please click on the link to read more about his circuit
I decided to make two small circuit board, the program I used is called PCB Wizard 3
this is an excellent program to use
I would like to thank Philip Gladstone for the information and help
on his design and sharing it
