In Linux, any device operations are abstracted as file read/write, read the content in the/sys/class/thermal/thermal_zone0/Temp File to get the Raspberry Pi CPU temperature. This article describes how to read and apply the temperature par

For different Raspberry Pi versions, the script files you write may not be generic.For example, the "GPIO 16" and "36" pins refer to the same, while the corresponding ones are defined by BCM, which is defined by "BOARD".V.

This assumes that you already have the Raspberry Pi 2/b+, and that it is already installed. If not, I suggest you buy one, they are both cheap and fun. Personally, I'd rather spend a little more money buying from Canakit. Their logistics quickly and reliably, plus their ready-to-go service is also very good. Okay, let's start OpenCV and Python installation.Step 0
