Remote access to Raspberry Pi Zero (Rpi Zero) is a popular choice among makers, hobbyists, and professionals in the field of Internet of Things (IoT). The Raspberry Pi Zero is a tiny, low-cost, and fully-functional computer that comes without a built-in Ethernet port. Therefore, remote access is one of the easiest ways to connect and interact with the Rpi Zero for various purposes such as data transmission, remote control, monitoring, and many others.
This article will explain the different methods that can be used to establish remote access to Rpi Zero and provide code examples that you can use to configure your own projects. The article will cover the following topics:
- Introduction to Remote Access
- Remote Access via SSH
- Enabling SSH on Rpi Zero
- Finding the IP address of Rpi Zero
- Connecting to Rpi Zero via SSH
- Remote Access via VNC
- Installing and Configuring VNC on Raspberry Pi Zero
- Setting up VNC Viewer on your Host Machine
- Connecting to Rpi Zero via VNC
- Conclusion
Without further ado, let's dive into the first method:
- Introduction to Remote Access
Remote access is a way to control another device remotely using a network connection. There are several ways to achieve remote access, including:
-
Remote Access using SSH: Secure Shell (SSH) is a secure protocol that provides encrypted communication between two devices. Users can use the terminal or command line to connect to a remote device, transfer files, and execute commands remotely.
-
Remote Access using VNC: Virtual Network Computing (VNC) is a graphical desktop-sharing system that allows users to control a remote computer graphically. VNC is useful for remote access to a remote computer, allowing users to see and interact with the remote desktop environment as if they were in front of it.
In this article, we will explore both methods in detail.
- Remote Access via SSH
SSH is a popular method for remote access to Rpi Zero as it provides a way for the user to connect to the Rpi Zero via the terminal or command line. It is also secure as an encrypted connection is established between two devices. Here's how to set it up:
Step 1: Enabling SSH on Rpi Zero
SSH is not enabled by default on Rpi Zero. Therefore, you will need to enable it first. To do this, connect your Rpi Zero to a monitor and keyboard, and then follow the steps below:
- Boot up your Rpi Zero and open the terminal
- Type in the following command: sudo raspi-config
- Use the arrow keys to navigate to 'Interfacing Options'
- Select 'SSH' and press enter
- Select 'Yes' to enable SSH
- Exit raspi-config by pressing 'Esc' and then select 'Finish'
If you do not have a monitor and keyboard available, you can still enable SSH by creating an empty file named 'ssh' on the boot partition of the Rpi Zero. This can be done by inserting the SD card into your computer and creating an empty file in the boot partition named 'ssh' with no extension.
Step 2: Finding the IP address of Rpi Zero
Next, you will need to find the IP address of your Rpi Zero in order to connect to it over the network. You can do this by typing the following command into the terminal:
ifconfig
This will display the network information for your Rpi Zero. Look for the 'inet' address in the wlan0 section. This is the IP address that you will use to connect to your Rpi Zero.
Step 3: Connecting to Rpi Zero via SSH
Now that SSH is enabled, and you have the IP address of your Rpi Zero, you can connect to it remotely using SSH. To do this, open your terminal on your host machine and type in the following command:
ssh pi@

- Remote Access via VNC
VNC is a graphical desktop-sharing system that allows users to control a remote computer graphically. This method is useful when you want to interact with the graphical user interface of the Rpi Zero remotely. Here's how to set it up:
Step 1: Installing and Configuring VNC on Raspberry Pi Zero
- Open the terminal on your Rpi Zero and enter the following command to install VNC: sudo apt-get install tightvncserver
- After the installation is complete, enter the following command to start VNC server: tightvncserver
- You will be prompted to enter a password for VNC. This password is used to authenticate VNC connections. You will need to enter this password each time you connect to your Rpi Zero via VNC.
- Once the VNC server is started, you can exit the terminal by entering the following command: exit
Step 2: Setting up VNC Viewer on your Host Machine
- Download and install VNC Viewer on your host machine from the official website: https://www.realvnc.com/en/connect/download/viewer/
- Open the VNC Viewer app and click on the 'New connection' button.
- In the 'VNC Server' field, enter the IP address of your Rpi Zero followed by the VNC port number (the default is 5901). For example, 192.168.0.10:5901
- In the 'Name' field, enter a name for your Rpi Zero.
- Click on the 'Connect' button.
Step 3: Connecting to Rpi Zero via VNC
- After clicking on the 'Connect' button, you will be prompted for the VNC password you set up earlier.
- Enter the password, and click on the 'OK' button.
- You will then be connected to your Rpi Zero, and you can interact with the desktop remotely as if you were physically connected to it.
- Conclusion
Remote access to Rpi Zero is essential for many IoT projects, especially those that require remote control, monitoring, and data transmission. SSH and VNC are popular methods for establishing remote access and can be easily set up following the steps outlined in this article. Regardless of which method you prefer, remote access to Rpi Zero is a powerful tool that can help you develop projects and accomplish your goals with ease.
here's some more information on each of the topics covered in the article:
- Introduction to Remote Access:
Remote access is a method for controlling a device remotely using a network connection. This can be useful for many applications, including IoT projects, server maintenance, and remote work. There are several ways to achieve remote access, including SSH, VNC, Remote Desktop Protocol (RDP), and others. Each method has its own strengths and weaknesses, and the choice of which one to use will depend on your specific needs.
- Remote Access via SSH:
SSH is a widely used method for remote access to Linux-based devices. It allows users to connect to a remote device using a secure, encrypted connection, and provides a way to execute commands and transfer files between the local and remote machines. SSH is especially popular among developers and system administrators, as it provides a way to manage servers and work with command line tools remotely.
- Remote Access via VNC:
VNC is a graphical desktop-sharing system that allows users to control a remote computer graphically. Unlike SSH, which provides a command-line interface, VNC provides a way to interact with the remote desktop environment and run applications remotely. This can be useful for many types of applications, including remote monitoring, remote control, and remote work. However, VNC requires more bandwidth than SSH, and may not be as suitable for low-bandwidth connections.
In general, SSH is a more lightweight and secure way to achieve remote access, while VNC is better suited for applications that require graphical interaction. However, the choice of which method to use will depend on your specific needs and the constraints of the network connection.
In addition to SSH and VNC, there are many other methods for achieving remote access, including RDP, Telnet, and others. Each method has its own strengths and weaknesses, and the choice of which one to use will depend on the specific requirements of your project.
In conclusion, remote access to Rpi Zero is an essential tool for many IoT projects, and there are several methods available for achieving it. By following the steps outlined in this article and choosing the right method for your specific needs, you can establish secure, reliable remote access to your Rpi Zero and take your projects to the next level.
