Let's say you want to monitor the chip temperature every 2 seconds. But if you want to monitor the CPU temperature at a regular interval, you can use the watch command: To see the current temperature of the system on chip (that consists of both CPU and GPU), use this command: vcgencmd measure_temp Raspberry Pi has a dedicated command line utility, vcgencmd, that shows various aspects of the Broadcom SoC, including its core temperature. Method 2: Monitoring Raspberry Pi GPU and CPU temperature in the command line You can change the colors of the applet or of critical points such as CPU frequency cap or temperature threshold. Right click on the applet and you can configure it to some extent. Now, you should start seeing the temperature of your processor chip: The SoC temperature changes continually CPU and GPU will show the CPU and GPU usage respectively (if you want that as well in the top panel). The 'Add to right' means it will be added to the right most corner of the panel. Select CPU Temp and click on Add to right and hit the OK button. Since most people are concerned with CPU temperature, it is named as CPU Temp even though it shows the temperature of the SoC (that houses both CPU and GPU). Right click on an empty space on the top panel. It will show you the current CPU (actually the SoC) temperature. If you are using your Raspberry Pi as a desktop system with Raspbian OS, you can add a handy applet to the top of your screen. Method 1: Monitoring Raspberry Pi CPU and GPU temperature using GUI tool You can take that as the temperature of both CPU and GPU. Raspberry Pi provides utilities that show the temperature for this SoC. In simpler words, the chip has both CPU and GPU in it.

Raspberry Pi uses a system on chip (SoC) from Broadcom which consists of an ARM processor (CPU) and an on-chip GPU.
