My DSLR-webcam is currently mounted on the southside of a roof.
At the moment germany is facing a strong heat-period.
So it's quite interesting to check the CPU-temp of the RaspberryPi.
You can do this by executing the following shell command:
vcgencmd measure_temp
In my case the output was today:
temp = 67.0'C
The datasheet of the CPU and also of the SD-card says that these parts have a 'operating temperature' of -25 to +85 °C.
Everything OK here.
Just the EOS1100D operation is out of range:
Canon limits the official 'working temperature range' to 0-40°C
