RMS-100v2 has an LM75 temperature sensor onboard to monitor board temperature!


Below is a screen shot of the RMS-100v2 temperature setup page. Preliminary setup steps are done in this area like entering notes and choosing the temperature format.






The RMS-100v2 web interface has High and Low triggers that can be set to fire alerts or scripts when the temperature is either too high or too low. Use the relay scripts to turn on a cooling fan for example. The High Trigger is used when the temperature rises above the High Trigger value. The Normal Trigger is used when the temperature falls below the High Trigger value.






Below is the Low Trigger interface. The Low Trigger is used when the temperature falls below the Low Trigger value. The Normal Trigger is used when the temperature raises above the Low Trigger value.





Temperature Triggers Explained



voltmeter triggers


When the temperature is within a trigger range (as shown by the different color bands), the action will only execute as often as specified by the "Execute Actions Below Every" pull down list box. If the temperature is in the green (Normal Range), and moves above the High trigger value (MIN) into the yellow, no actions occur. Only if the temperature moves into the red range (past High Trigger Value (MAX)) will the action occur. If the temperature flutters into the yellow and back into the red, this does not reset any triggers. The High Trigger condition will reset only when the temperature falls back into the green where it will execute the "High Normal Trigger" action only once.

The same theory applies to the Low Trigger values. If the temperature is in the green (Normal Range), and moves below the Low trigger value (MIN) into the light blue, no actions occur. Only if the temperature drops into the dark blue range (past Low Trigger Value (MAX)) will the action occur. If the temperature flutters into the light blue and back into the dark blue, this does not reset any triggers. The Low Trigger condition will reset only when the temperature rises back into the green where it will execute the "Low Normal Trigger" action only once.


Below is an example of reading the temperature on the command line. Note: the file tempf contains the board temperature in Fahrenheit. The file tempc contains the board temperature in Celsius.
