The 1lb Boxed Screw Storage Rack
So I have been pondering the idea of making something similar, except replacing the reed switch with an IR sensor. Drill a 1" hole in the back of the mailbox and install the sensor in the hole, seal it up good and wire it to the Arduino for the switch. SInce the receiver portion will be in the house, I plan to set it up to send me a text message when mail is delivered. It will also tell me if someone else opens the mailbox before me.
I just found you question and was wondering if you ever figured out how to add the additional sensors? I would like to do the same so I can name the different sensors (zones) so when activated, it will tell me what area was activated. Thank you for your time.Randy firstname.lastname@example.org
