Thermal Tests

To determine whether a companion pc is capable for use in a closed capsule inside the drone, the temperature, power usage + ???( e.g. run algorithms) needs to be measured which is needed in a similar setup.

Methodology

  • put the unit into a box
  • connect camera
  • trigger a camera shot every second
  • measure temperature by using onboard sensor
  • measure average power usage by using external power meter
  • run the test for at least 30 minutes
