Remote temperature and/or bilge reporting
 

We have a boat that, from time to time, suffers a heating problem.

We'd like to install something that would monitor the air temperature, and if
it fell below a certain level, would call a pre-programmed number. A plus
would be for a unit that can also report high water in the bilge.

I've seen devices you call into, but that will not work as the phone there has
voice mail on it.

As an alternative, are there any devices that can monitor a home and can
provide continuous reporting via the internet?

Thanks

Hi Gary,
I have a low temperature detector for the house. It calls a preset
number when the house temp. falls below a set (adjustable) level. It keeps
trying through busy signals and leaves a message. It needs 120 volts AC and
a phone line. It is called a Freezealarm by Control Products Inc.. Good
luck.

You can find lots of this kind of thing by searching for "home

Assuming you have a phone line at the dock, go to a Alarm system and
security supplier and ask for a voice dialer. The one I use for an on
land application plays 3 messages (chosen by one of three trigger
inputs) to upto 3 preprogrammed phone numbers. Hook one input via a
domestic thermostat switch to +12V (needs a 12V pulse or level to
trigger) and program that message as 'frost alarm', hook the next one up
via a float switch in the bildge slightly higher than your bilge pump
and program that as 'bilge flooding' and hook the last one to the
contacts of a mains voltage relay with the coil hooked to your shore
power, message 'power lost' so you can be sure your batteries are
getting their trickle charge. If daysailing occasionally, LEAVE IT
PERMANENTLY POWERED BY +12V as they tend not to have a backup battery
for the message memory and phone numbers. You might want a switch to
disconnect the three inputs to disable it.

There are certainly small single-board computers that can maintain
simple web sites. Weatherbug is an example of such use. Web cams that
monitor hawk nests and the like are another.

You would have to get a continuous internet connection at the boat. I
think the autodialer that calls sounds much cheaper, but maybe it
isn't always.

If the marina has wifi available, that might be the cry.

The refinery I used to work at installed a device that called a
pre-programmed phone number whenever there was an alarm in the waste
water management panel. They got it at Radio Shack for about $100.00.
