Re: [PLUG] How to Signal from a Modem?


I second the sensaphone item. I've used 'em as well in many places.
They work very well.

I would look to using some kind of stand-alone, battery powered, box.

Historically, Sensaphone, (www.sensaphone.com) provided a reliable and cheap
 "black box" that would dial out over POTS when any of a a number of different
sensors triggered a "situation."

You could also dial in to the Sensaphone and it would tell you things like time
and temperature and allow you to listen to the environment where the box was
located.

I have used these to monitor Computer Room status for many years
(since about 1980!)
They are "relatively" cheap for what they do and their reliability.

Back then Sensaphone was the only game in town... today there are
undoubtedly Chinese
knock-offs that are cheaper.

Sensaphone now has a stand-alone "web based" version that will send out text or
email messages.

I just picked up (It came in the mail today, so I haven't tried it yet.)

Ran across an interesting I/O module and wondered if anyone had used this

8 digital outputs
8 digital inputs
8 temperature inputs (one wire)
3 analog inputs
Humidity sensor input

Also has some timer functions and can sent email alerts on a condition.
Probably not that useful if used with mh...

It has hardware for RS232/485 but it is not supported by the software.  This
would be more useful than email status or
