[App_rpt-users] temperature sensor

[Robert A. Poff WB3AWJ]

The simplest would be to mount a thermal switch on the heatsink. When it closes fire a GPI. 



Something like this at the temp threshold that you want to alarm:

Find out the temp were it's failing now, and select a switch maybe 5 or 10 degrees lower. 



For the room temp, maybe a plain old thermostat tripping a different GPI. 

Using one for AC/HEAT would give you high and low trip points. 



This would at least give you some alarms.

I am having a problem with the hot weather shutting down a repeater. I would 
like to know if anyone has any way of monitoring the ambient temperature in 
the room as well as the surface of a heat sink and then triggering an event 
in app_rpt when they exceeded a certain threshold.
