How to Monitor CPU Temperature and Status of Raspberry Pi

Companies and business organizations must manage a huge fleet of IoT devices to manage their business operations. If you want to operate your IoT fleets reliably and properly, you need to maintain comprehensive data about the health status of all your IoT devices, along with a system error log for diagnosing and troubleshooting application and device hardware problems. In other words, companies must monitor IoT to perform their daily tasks seamlessly.

Monitor CPU Temperature Raspberry Pi

Remote IoT offers insights into the disk, memory, and CPU utilization of organizations' devices. This enables companies to monitor device hardware metrics, network performance data, system error logs, and CPU temperature of their IoT devices in a single dashboard. Once you install the Raspberry Pi service, you need to open the portal of remote IoT and click a single device. All the overview details will be provided on the page, such as

  • The serial number
  • Device model
  • Host name
  • Operating system

Monitor Raspberry Pi

You can see the health status of the Raspberry Pi system on the tab of usage graphs. Here in this tab, you can learn about the temperature and performance of Raspberry Pi devices. Following are the available graphs on the usage graphs tab

  • Memory utilization
  • CPU utilization
  • Free disk space
  • CPU temperature
  • Network in as well as network out
Now, if you want to troubleshoot and diagnose all the hardware issues like USB problems or hard disk errors, you can check the system kernel messages on the system error log tab.

Monitoring the CPU temperature and status of Raspberry Pi device
Raspberry Pi is an extremely powerful device, and so people use Raspberry Pi devices to perform specific intensive jobs that may decrease the last drop of the CPU power from the Raspberry Pi device. By overclocking, you can make your Raspberry Pi device more powerful. It consumes less power compared to the CPU of your computer desktop. However, similar to a computer device, Raspberry Pi can also become hot on performing heavy-duty tasks.

Humidity and temperature are two important data points in the present industrial world. Monitoring these two data for commercial freezers, server rooms, and production lines is important to ensure that everything is running smoothly. You can use three Raspberry sensors which are easy to connect and provide readings about CPU status and temperature. The three different sensors that help to monitor the temperature and humidity are as follows

  • BME280
  • DSB18B20
  • DHT22

Raspberry Pi also comprises sensors and tiny joysticks. You can get accurate temperature readings about your Raspberry Pi device using a ribbon cable.

Do you need to check the core CPU temperature and status of Raspberry Pi?
People often want to monitor and check the core temperature of the Raspberry Pi device. If you are performing intensive tasks which require a long-running Raspberry Pi CPU, then you need to constantly check the core temperature of your CPU. A notable feature of the Raspberry Pi device is that it is a low-end mobile computer, and it does not come with fans that can cool down easily like laptops, CPUs, or desktop CPUs. So you must keep the temperature and health status of your Raspberry Pi device in check.

What will happen if the Raspberry Pi device gets too hot?
You will see a small thermometer if the CPU temperature of the Raspberry Pi device rises more than 80 degrees Celsius. The thermometer displayed on your Raspberry Pi desktop indicates that the CPU is getting hot. The thermometer of Raspbian devices starts getting filled up with a constant rise in the CPU core temperature. It becomes a full thermometer when the core temperature reaches 85 degrees Celsius. This is the maximum limit of operating temperature in Raspberry Pi. Your CPU will throttle after crossing this temperature and lower the clock, which cools down the CPU temperature. On getting too hot, the Raspberry Pi's performance may get hampered. Therefore you need to check on your CPU and monitor the core temperature. You can also write a small Python script to check the temperature and the status of your device.

How can you measure the status and core temperature of your Raspberry Pi?
For measuring the core temperature, you can follow the below command in the terminal of your Raspberry Pi device. This will give you details about the core temperature of Raspberry Pi in Celsius.
  • You can create a Python script for monitoring as well as printing the CPU temperature every time.
  • Constantly check the temperature.
  • Use VNC or SSH to log into your Raspberry Pi terminal.
  • Create a Python file monitor, issue a command, print the temperature in the console, and save the file. You can now run Python to see the updated status and core temperature.
  • If you want to stop the Python script, press Ctl+C in the Raspberry Pi terminal.

You can monitor and measure the temperature and health status of the Raspberry Pi device. You can also modify the Python script to start a cooling fan or play a buzzer if the CPU temperature crosses a particular limit.
