If you’re looking for a way to keep tabs on your PC’s hardware stats and health in real time, a Raspberry Pi system monitor might just be the answer.

By building your own Raspberry Pi system monitor and using a tool like ModBros, you can track crucial metrics including CPU usage, RAM, and network connection status. It also allows you to detect potential issues early and optimize your PC’s performance.

In this guide, we’ll show you step-by-step how to build your very own Raspberry Pi system monitor, from installing the necessary software to customizing the display.

Whether you’re a seasoned DIY enthusiast or just looking for a fun project to dive into, this guide has got you covered. So grab your Raspberry Pi and let’s get started!

Do You Need A Raspberry Pi System Monitor For Your PC?

Real-time monitoring of a PC’s hardware stats can help identify and prevent potential issues in several ways. For instance, if the CPU usage is consistently high, it could indicate that there are too many programs running in the background, leading to slow performance or overheating issues.

By identifying this issue early through real-time monitoring, you can take action to optimize performance, such as closing unnecessary programs or improving ventilation.

Similarly, monitoring RAM usage can help detect memory leaks or times of insufficient memory, which can cause crashes and freezes. By identifying these issues early, you can take steps to resolve them before they cause significant damage or data loss.

Additionally, a system monitor can provide valuable information to help you identify and diagnose problems when troubleshooting issues. By building a Raspberry Pi system monitor for your PC, you can take control of your system’s performance, keep it running smoothly, and save yourself the frustration of dealing with unexpected system failures.

Installing The Software

To get started with monitoring your PC’s hardware stats using MoBros, the first thing you’ll need to do is install the server software on your PC. 

Install the MoBro server software on your PC:

  1. Go to the official ModBro website and download the software.
  2. Follow the installation instructions provided on the website.

Download the MoBro client software for your Raspberry Pi:

  1. Now download the client software for Raspberry Pi by clicking here.
  2. Download the Raspberry Pi Imager software.

Install the MoBro client software on your Raspberry Pi:

  1. Insert the SD card into your desktop’s card reader.
  2. Boot up the Raspberry Pi Imager app.

  1. Select the MoBro client software image file you’ve already downloaded.
  2. Tap on the “Choose SD card” button and choose your SD card from the list.
  3. Click “Write” to write the software to the SD card.
  4. After the software is written to the SD card, press “OK” and remove the card.

Setting Up The Raspberry Pi System Monitor

Once you have done all of the above, you’re ready to move on to the next step and start setting up and configuring your ModBros Raspberry Pi system monitor.

  1. Insert the newly prepared SD card with the MoBros system monitoring software into your Pi device.
  2. Mount the Pi over the display’s PCB using the standoffs provided.
  3. Connect the display’s cables to the Raspberry Pi.
  4. Connect the Pi’s GPIO pins to the Ground pins of the screen PCB.
  5. Mount the display and Pi device inside the covering case and properly secure it using screws.
  6. Connect the internet LAN cable to the Pi’s network port and your WiFi router.
  7. The software on the Raspberry Pi should automatically detect the server application on your PC and display the default information once it’s booted if you’re using a wired internet connection.
  8. If you’re using WiFi, connect to the hotspot created by the Pi device from another computer and navigate to the IP Address shown.
  9. Then after connecting your Pi device to your home network. You should be able to see the default system info from your web server.
