[…] USB. I’ve been using it with my Raspberry Pi for as a simple CPU temperature readout, as you can read in my earlier post. Working on that temperature readout utility taught me how to communicate with the micro:bit and to […]

It keeps me off the streets.

As another data point, I moved the code and hardware over to my Raspberry Pi 3 Model B Plus Rev 1.3. Idle temperature is 48 C. That’s 27 C lower, and this is with the same OS (Raspbian Buster) running on both. Yes, the 3B+ is slower, but I contend the temperature should be higher on the 4, it shouldn’t be that hot on the 4.

Sounds like an interesting pastime.

First of all it’s not supposed to be this high, especially under idle (i.e. no load). Second, I want to keep an eye on the temperature as I work with this and see how higher it gets. If it gets high enough then the CPU will throttle back. Finally, temperatures this high in shirt-sleeve ambient temperatures are never a good sign, especially if you want to use this as a base for an unattended system performing some continuous task.

These temperatures are all in Centigrade. The typical idle temperature on this board’s CPU of 75 C is 167 F.

How does knowing the temperature assist you?
