12/25/2022 0 Comments Raspberry pi 4 cpu temp monitor![]() ![]() You can store the value in a database and create graphics or tables with it after that. Using GPIO Zero with Python is probably the best way to build a temperature logger on Raspberry Pi. PiCar-X is an AI self-driving robot car for Raspberry Pi. It worked directly on Raspberry Pi OS, so you shouldn’t need anything, but if the GPIO Zero library is not installed on your version, you can install it with: Print("CPU temperature is "+ str(cpu_temp)+"☌") On Raspberry Pi, the GPIO Zero library is installed by default and can give you the current temperature with the CPUTemperature() class.Ī basic script can look like this: from gpiozero import CPUTemperature There are several ways to get the CPU temperature in Python. Monitor the Raspberry Pi temperature with Python If you are using Python in your scripts, I have another option for you. This can be particularly handy to add downtime in a long script when the CPU temperature is too high, for example.Īre you a bit lost in the Linux command line? Check this article first, for the most important commands to remember, and a free downloadable cheat sheet so you can have the commands at your fingertips. You can also use these commands in Shell scripts. This will be particularly useful if you are using Raspberry Pi OS Lite, or connect to your Raspberry Pi via SSH. You’ll get the temperature in degrees Celsius, something like: On Raspberry Pi, there is a command line that can be used to get the current temperature: Check the Raspberry Pi temperature in the command line If you are lost in all these new words and abbreviations, request my free Raspberry Pi glossary here (PDF format)!īy doing this, you’ll always have an eye on it and can see if a cooling system is necessary or not. You can also change the thresholds if you want (the color will be different when the CPU is too hot, so you’ll notice it easily). ![]() You can move the widget by using the “Up” and “Down” buttons and clicking on “Preferences” to change the colors. In my case, it was 46 ☌ at the time I took the screenshot. Close everything, and you should now see the current CPU temperature in the top bar:.Choose “Temperature Monitor” in the list and click on “Add” again.Go to the “Panel Applets” tab and click on “Add”:.Choose “Panel Settings” in the drop-down menu.Do a right-click on the blank spot in the top bar.On Raspberry Pi OS with Desktop, the easiest way to see the CPU temperature is to add the Temperature Monitor widget in the top panel. Raspberry Pi OS Desktop: How to keep an eye on the temperature? I will give you several ways to do this on Raspberry Pi OS, some of them should work on other systems too. Let’s learn how to check the current temperature of your Raspberry Pi in order to see if you need to cool it or not. How to monitor the CPU temperature on a Raspberry Pi? But over time, not cooling down the CPU can lead to bad performance and a reduced lifespan. In theory, a Raspberry Pi can’t overheat, as there is a mechanism to slow down the CPU when it’s too hot. In this case, having a basic cooling system and keeping an eye on the CPU temperature are recommended. The CPU temperature can be an issue if you have tasks using the processor for a long period, without downtime (heavy scripts, crypto mining, gaming, etc.). Get all the information on this page if you are interested.ĬPU Temperature evolution during a 5-minutes stress test You’ll also do your first project with me, just to make sure you are ready for the next level. I’ll help you use the perfect hardware, plug everything in and install your first system. If you need help getting started on Raspberry Pi, I have an entire course to guide you through your first steps. I’ll answer your questions in a Q&A format in this article, so feel free to jump directly to the one you are interested in or read everything in the logical order to master this topic. Cooling is not mandatory for normal usage but can help maintain top performance all the time. It will start throttling (reducing performance) as it approaches this threshold in order to prevent overheating. In short, the CPU temperature of a Raspberry Pi must stay below 85 ☌ at all times. Do you need to cool the thing? If so, what is the ideal temperature range? How do you know the current CPU temperature? If you have any doubts, you are at the right place! I will answer all your questions in this article. When you buy a Raspberry Pi board, you are on your own. ![]()
