I am trying to work with the telemetry page on FindU. I have a
telemetry value that requires the attached math to make it display
the way I want. I haven't figured out how to make the math work to
get it to display correctly. Any help would be appreciated.
I am reading telemetry parameter 1.
I need to take the value (Currently sitting on my bench in an air
conditioned room!) with a value of 148
I would LIKE to have the value in Degrees F (I know that C would be
So here is the formula:
((Telemetry + Correction Factor) X 1.9608 Sensor Multiplier - 273.15)
* 5 / 9 - 32 = F
For this install the correction factor is 4.7.
1.9608 is the sensor multiplier (Constant)
The rest if just the basic math...
I don't understand how the a= b= and c= can get me there!
Any help would be appreciated!
(I have figured out the easy linear ones in the past - Like this same
one for voltage -
(FYI - This is the output of an OpenTracker+ being used in an outdoor
solar only radio site (Emergency Clinic) to record interior
temperature for the batteries and battery voltage. - I do have it on
the status line, but I don't like the resolution, and would like to
plot it like I have done for the voltage) http://map.findu.com/purg
