I'm talking about those standard roadside USPS boxes.

Mine's in front of the house and I'm wondering if there's a gadget that can
tell you by sight, or maybe electric trip switch, if there's something in
the box.

At a previous employer, our mailbox was a quarter mile from the office.
We had a device with a tilt switch and a radio transmitter that detected
when the door was opened, rining a bell in the front office. Don't know
where he got it, other than it was from a mail-order catalog.


The radio notification devices may not work for everyone. Reception
problems due to weak signals can occur if the distance is too great.
The transmitters require batteries and may experience problems during
temperature extremes.

My (rural type) mailbox is just about 30 feet from the house, with
nothing but air in between. However, none of those RF devices I've
ever tried would work reliably. If there's any interference, the most
likely source seems to be the box itself (heavy steel).
