Some outboard repeater controllers have an analog input made especially for an RTD (Resistance Temperature Detector) element. All you have to do is purchase the correct RTD sensor (a few bucks) and connect it to the controller with shielded twisted-pair cable. A few simple calibration steps, and you're done. Nothing could be simpler.
The controller can be programmed to respond with a voice announcement of the temperature with a DTMF command, or you can program it to automatically broadcast a warning message if the temperature is not within the programmed setpoints. I believe that Link offers this feature on several models, and so does Pacific Research. Others must do the same... 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Charles Schmell Sent: Sunday, January 21, 2007 9:27 AM To: [email protected] Subject: Re: [Repeater-Builder]Transmitting interior temperature I believe the CAT line of controllers can interfeace to a Davis or Peet weatherstation, reading all the parameters including temp, back through the repeater. Check out info at www.catauto.com. I have no affiliation, just have a CAT-1000 on the club repeater. (no wx interface, though) Think others can do the same, although it's pricey if you have to buy a new controller plus the weather station. The talking thermometer sounds like a neat and inexpensive solution, though Chas, KB3CEZ > -------------- Original message > ---------------------- > From: "Butch Kanvick" <[EMAIL PROTECTED] <mailto:hotlrv%40hotmail.com> > > > I have a 440 repeater at a high mountain location. > > I would like to know the interior temperature of > the repeater building. > > The building is heated. > > Does anyone know how I can connect a voice sytem > to the 440 repeater to > > transmit the temperature, when the repeater ID's? > > > > Any ideas will be greatly appreciated. > > > > I might have to use a data link to retrieve the > information also. > > > > Thanks, Butch, KE7FEL
