Greetings Shawn,
I had to take the M600 to extreme heights where the cold might effect the electronics for a military experiment, so without fitting an independent transmitter and sensor array I simply bought a small but good low temperature unit with a large display and probes and fitted it to the craft. Then used the second camera option the LB2 has and just pointed a mobus camera at the display, focused and then used a second controller to view the numbers, if you don't have a second display you can attach a monitor to the hdmi on the controller and do picture in picture. PiP only works in external monitor or use video goggles direct to the Hdmi out. I now have a thermal camera so the above sits on the shelf. I am developing a range-finder using the same system because it worked so well. 4000m (13,000ft) in protected airspace and the craft was at -11ºc and batteries at 30% after 15mins, video signal ok, transmission signal orange. Major problem was fogging of the lens until it thermally stabilised.
There is another bit of software that has telemetry and reports temperature and thats is Auto flight logic, I am beta testing and it has some great features but is not designed for a two camera setup. I don't know where the sensor is on the craft however I expect it to be in the flight controller or IMU, as this is where the most sensitive electronics live. . I did get the M600 back in good shape, plenty of condensation though.
One other method I have used is thermal paint, it changes colour with heat and stays that way so when it lands you can see what temps the craft was exposed too, not hi-tech but effective and we use it in F1 all the time. I suppose you could use a max min thermometer and review when landed.
If you want further info please feel free to ask
