  • Educational Opportunities: Raspberry Pi serves as an educational tool, and by building a PC monitoring project, you can learn about various aspects of computer hardware, software, automation, and networking.

What You Need to Prepare?

You will need the following basic items and materials to set up your Raspberry Pi performance monitor:

  • Raspberry Pi: Raspberry Pi is the primary hardware platform, and you can choose a model that suits your needs, such as Raspberry Pi 3, Raspberry Pi 4, etc.
  • Power Adapter: Provide a stable power supply for the Raspberry Pi, typically using a 5V power adapter.
  • MicroSD Card: Use it to store the Raspberry Pi's operating system. It is recommended to use an 8GB or larger capacity SD card.
  • Keyboard and Mouse: Needed for initial Raspberry Pi setup.
  • Computer or Laptop: Required for configuring the Raspberry Pi during the initial setup.
  • HDMI Display: Used to connect to the Raspberry Pi for initial setup.
  • Network Connection: You will need a reliable network connection, which can be Wi-Fi or Ethernet.
  • Sensors and Modules (Optional): Depending on your monitoring needs, you may require various sensors such as temperature sensors, humidity sensors, motion sensors, etc.
  • Enclosure or Case (Optional): Provides protection for the Raspberry Pi and related circuits to ensure device safety.

Download and Install Required Software:

1. To set up your Raspberry Pi hardware monitor. We need to access the Mobro website (https://mobro.app/) and download and install the Mobro APP.

Mobro APP

Once installed, open Mobro, but you don't need to operate it for now; just keep it running.

2. Download the MoBro Raspbian image from the MoBro official website and extract it.

3. Download the Raspberry Pi Imager from the Raspberry Pi official website (https://www.raspberrypi.com/software/).

4. Launch the Raspberry Pi Imager, click "Choose OS," select "Use Custom," and write the MoBro Raspbian image to the MicroSD card.


5. DO NOT apply OS customisation settings.


6. After the write process is complete, insert the SD card into the Raspberry Pi.

Setting Up Mobro for Raspberry Pi:

After powering on your Raspberry Pi, connect it to your network for setting up the Raspberry Pi system monitor web interface. If using Wi-Fi, the Raspberry Pi will create a 'MoBro_Configuration' access point for network setup. Once configured and connected to your Wi-Fi, the Raspberry Pi will locate the MoBro instance on your PC within the same network, enabling web-based monitoring of your PC.

1. Connect a screen to the Raspberry Pi and power it on.

2. If you've connected the Raspberry Pi to your network using an Ethernet cable (ensure it's on the same network as the PC you want to monitor), the setup process is straightforward; you'll just need to wait for a moment.

3. If you intend to use Wi-Fi for your Raspberry Pi:
a) After a short while, the Raspberry Pi will create a wireless access point named "MoBro_Configuration." You will enter essential information like your SSID and password for your Wi-Fi network here.

c) After completing and applying the configuration, the Raspberry Pi will restart and automatically connect to your Wi-Fi network. It will then search for the MoBro instance running on your PC within the same network.

Edit the User Interface (UI):

Once the Mobro Raspberry Pi is connected to your PC, a new dashboard will appear in the MoBro app on your PC. Now it's time to customize it.
