I know this is way over kill for your situation but I took two of these
devices: <http://jeelabs.net/projects/hardware/wiki/JeeNode>, a photo
sensor: <http://shop.moderndevice.com/products/ambi-light-sensor> and
a 250V neon panel indicator light and built a system that allows my linux
box to record my well pump activity. The indicator light is wired in
parallel to my pump and lights up when the pump turns on. One of the
JeeNodes looks at this light every second and sends a message when the
light changes state. The other JeeNode receives the message and talks
via USB to a program on my linux box. Right now the program only keeps
track of when the pump cycles on and off but it could be changed to
send mail or some other kind of alert if the pump is on for two long.
The sending unit/sensor is in my unfinished basement where as the
received in on the first floor of the house about 40 feet from the
sender. Right now the sender is battery powered and 4 AA's lasted about
24 days.
