How do I monitor the temperature of my Raspberry Pi?
Using the ” code in a terminal window is the simplest way to calculate the condition of your Raspberry Pi:
vcgencmd measure_temp
The temperature will be shown in degrees Celsius:
temp=31.0'C
You can use the following formula to get the number:
vcgencmd measure_temp | egrep -o '[0-9]*\.[0-9]*'
This sends vcgenmd's production to egrep. The characters that are numbers following a full stop character are then output.
If you want to keep an eye on the temperature all the time, use the watch command:
watch -n 2 vcgencmd measure_temp
The temperature will be shown, and the value will be updated every 2 seconds.
Must Check:
The Raspberry Pi OS Desktop now has a temperature Display.
You should add a temperature gauge to the top panel where the clock is mirrored if you're using the Raspberry Pi OS desktop. This makes it very simple to keep track of the importance while you do various tasks:
My Pi is currently at 35 degrees Celsius in this case.
To add the temperature to the top column, follow these steps:
- Select the top panel with a right-click.
- Select “Add / Exclude Panel Items” from the drop-down menu.
- Activate the “Add” button.
- Select “Temperature Monitor” from the list at the bottom.
- Activate the “Add” button.
- Place the display above the "Digital Clock" by pressing the "Up" button.
You can add any space between the panel objects by doing the following:
- Select the top panel with a right-click.
- Select “Add / Exclude Panel Items” from the drop-down menu.
- Activate the “Add” button.
- Select “Spacer” from the list at the bottom.
- Activate the “Add” button.
- To move the spacer, press the "Up" or "Down" buttons.
- Set the height of the spacer using the "Preferences" button.
To create a sensible difference between the temperature reading and the surrounding panel objects, I used 10 Spacers.
You will alter the levels and colours that are used by:
- In the top column, right-click on the Temperature.
- Select “Temperature Monitor Settings” from the drop-down menu.
- Adjust the settings as needed.
- To save, click "OK."
You may adjust the thresholds at which the alert colours appear.
Python temperature reading
The Gpiozero library makes reading the Pi CPU temperature in Python pretty simple. Simply provide the following code at the top of your script to import the library:
import gpiozero as gz
The temperature was then recorded in a variable:
cpu_temp = gz.CPUTemperature().temperature
You should add the line: if you want to round the value to one decimal place.
cpu_temp = round(cpu_temp, 1)
Once you've stored the temperature value in the variable, you can print it, record it to a register, or email it to a database.
Bash temperature reading
You may use the following command to read the temperature from inside a Bash script:
temp=$(('cat /sys/class/thermal/thermal_zone0/temp'/1000))
echo $tempYou'll get an integer answer of no decimal points, which shouldn't be a problem with most applications.
FAQ (Frequently Asked Questions)
Is a cooling fan needed for the Raspberry Pi 4?
A fan is required for the Pi 4. A heatsink mounted within the official Pi 4 case can do nothing to prevent the CPU from throttling (and likely other components, as they all get very hot)
What is the procedure for installing a fan on my Raspberry Pi 4?
No instruments are required; simply position the Raspberry Pi in the case's newly generated portion. The Raspberry Pi is tightly held in place by a two-piece injection-molded ABS enclosure with snap-fit mounting points. Pop off the top of the Pi box, line up the Case fan inside the top of the case, and press it in before the tabs click into place to mount the fan.
Is a case needed for the Raspberry Pi 4?
The Raspberry Pi 4, 3, and even the Pi Zero have the best examples. Even though a Raspberry Pi can function without a case, many people choose one that protects the single-board device while still providing an appealing interface, built-in cooling, or even special features.
What's the best way to keep my Raspberry Pi 4 cool?
The best cooling option for the Raspberry Pi is the SB Components Cooling Fan case. It keeps the Pi CPU close to average temperature when it's idle, and it never gets above 50°C when it's fully loaded.
What happens if a Raspberry Pi gets too hot?
Using the hardware under certain conditions for long periods of time, on the other hand, will shorten the Pi's lifetime. More immediately, you can see thermal throttling, which ensures that the system's total speed is decreased to allow it to breathe.
Is it essential to use a fan for the Raspberry PI 3?
The CPU in PCs and laptops has a fan to keep things cold because they get really hot and can be fried if not. Since the Raspberry Pi's CPU has low power requirements, it does not need cooling to prevent harm.
What is the best way to control the fan on my Raspberry Pi?
Install a fan on a Raspberry Pi 3 and control it on and off as required. Connecting the fan leads to a 3.3V or 5V pin and ground is a simple way to add a fan. The fan would work continuously if this method is used.
On a Raspberry Pi 3, how can you mount a cooling fan?
Pop off the top of the Pi box, line up the Case fan inside the top of the case, and press it in before the tabs click into place to mount the fan.
When it comes to the Raspberry Pi 3, what temperature is too hot?
A 'soft' temperature cap of 60oC has been added to the Raspberry Pi 3+. This ensures that the clock speed is lowered from 1.4GHz to lower frequencies even before hitting the hard limit of 85oC, lowering the temperature increase on the components.
What is the best temperature for Raspberry Pi to run at?
The temperature of the Raspberry Pi ranges from 0 to 85 degrees Celsius. The CPU is temperature-qualified from -40°C to 85°C, while the LAN is temperature-qualified from 0°C to 70°C.
How can I find out what temperature my Raspberry Pi is at?
A small thermometer will appear on your Raspbian desktop if the temperature increases above 80°C. This means that the Pi is overheating. The thermometer fills up as the central temperature increases. It then switches to a complete thermometer at 85°C.
