Save your changes and execute usermod -a -G video Debian-snmp Typically, the Raspberry Pi works fine without a cooling function, because even after hours of handling heavy loads of data, the CPU does not reach the maximum permitted temperature of 85C. Note the community string is case sensitive. Replace the word “public” with different community string.

The temperature of the CPU rises with the excessive use of the Raspberry Pi 4 which can damage the board. The temperature of the Raspberry Pi 4 is displaying on the top of the menu bar as highlighted in the figure below: Once the position is set, click on the “Close” button: Set its position on the menu bar, as we want to set it between the Spacer and Digital Clock, we will place it in between by using the “Up” button: We can also use the graphical user interface to monitor the temperature and can set it on the top menu bar so it will continuously display the temperature of the Raspberry Pi 4, for this purpose, we will right-click from the mouse on the top menu bar of the desktop of Raspberry Pi, a drag-down menu will appear, choose the “Add/Remove Panel Items…”:Ī window will appear, click on the “Add” button:įind out the “Temperature Monitor” and click on the “Add” button to add it on the title bar of the desktop: RASPBERRY PI 4 CPU TEMP MONITOR HOW TOHow to monitor the temperature of the Raspberry Pi by using a GUI If we want to display the temperature of the Raspberry Pi through the bash command, we will display the “/sys/class/thermal/thermal_zone0/temp” where the temperature of the Raspberry Pi 4 has been stored, for this purpose, we will use the command: How to monitor the temperature of the Raspberry Pi by using a bash command RASPBERRY PI 4 CPU TEMP MONITOR CODEThe output of the above Python script to monitor the temperature can be checked by running the python code using the command: $ python temp.py Finally using the print command, we have printed both values on the screen. Then use the round() function to round off the store value of the temp variable and store it in the round_temp variable. #printed the values of temp and round_temp variablesĮxplanation of code: In the above code, we have to import the library of the gpiozero and then find out the CPU temperature and store the value in the “temp” variable. Print ( "Temperature's value rounded to one decimal:" ) Print ( "The temperature of Raspberry Pi:" ) #round the value of temperature to one decimal #save the value of temperature of Raspberry Pi in "temp" variable ![]()
