Open Circuit, Time of Event, Data Logger (Door Log)

by jfuetterer on Thu Oct 21, 2021 7:15 pm

I am looking to make a logger that records the time of event when a switch is open. In other words, a door log to indicate when it is open. What hardware would I need to pull this off? I intend to import the timestamps into an excel spreadsheet. I am super new with this sort of thing and your help would be greatly appreciated!

1) Some form of switch:
magnetic reed switch (PRODUCT ID: 375)
light emitter & receiver (broken beam switch, PRODUCT ID: 2122)
reflected light detector. (PRODUCT ID: 164)

2) A microcontroller
Raspberry Pi Zero W - you can use ssh to look at your log over the internet, or sftp to download it.
Arduino - various
Feather - various

3) A case to put it in

4) Software to make it work.
