IoT Using Raspberry Pi

Raspberry Pi are microcomputers which are known for their power-packed performance that they can handle complex/big IoT based operations. therefore, It is used for handling complex logical operations and those which require high performance. The raspberry pi is a series of SBC’s i.e. the Single-Board Computers which basically consists of microprocessors, input/output features which makes it a fully functional microcomputer.

Which one to choose?



When building an IoT project, it must have struck your mind which board to choose from the wide range of boards available, Raspberry or not, right? Well, the answer comes out to be completely subjective to the IoT architecture, the number of I/O pins or GPIO’s, tasks the IoT is also capable of handling, the outcomes expected and the dynamics or flexibility one wants to have in their IoT product.

Raspberry PI Specialties

We consider Raspberry PI when

  •  The need for more computational capabilities.
  •  Requires ability to run multiple programs
  •  Have a fully functional Operating System(OS).

These features distinguish SBC’s like Raspberry PI from boards like Arduino which are used mostly for a single task or program iteratively.

variants of Raspberry PI

  1. RASPBERRY PI 4 Model B
  2. RASPBERRY PI 1 Model B+
  3. PI 1 Model A+
  4. RASPBERRY PI 3 Model B
  5. RASPBERRY PI Zero W
  6. PI Zero
  7. RASPBERRY PI 400
  8. RASPBERRY PI 3 Model B+

Are the alternatives a good choice for IoT using Raspberry Pi project?

It’s a Smart Choice.

When it comes to the other boards for IoT, the most popular ones are Arduino boards with a wide range of differences built up for in-general and specific purposes. Getting an Arduino board is a smart choice when your IoT model is designed to do a task on a repetitive count. so, It is preferred over a Raspberry Pi board for a single program based problem. But IoT using Raspberry pi is always above in terms of performance, processing and complexity handling

OS Compatibility

though Arduino comes with Arduino’s Integrated Development Environment(IDE) to program the board which does require an external computer for the job.

When it comes to Raspberry PI’s, the OS compatibility is very versatile and can be changed just by changing the memory space which holds the Operating System in it.

Programming Language Support

The support of programming Raspberry PI is also in different programming languages like C++, Python etc… 

however, it provides great flexibility to the programmer and brings ease to choose one’s own language.

Price vs Boards

Arduino has more low-cost boards when compared to Raspberry PI and both share a similar price range for some boards as well. But definitely Raspberry PI is generally more expensive in comparison to Arduino boards.

Community Support & Resources

Both Raspberry Pi and Arduino have good community support, a plethora of resources for their audience.

Speed, matters?

Well, Speed is more prominently based on the programming approach to the task 

Although apart from the different range of IoT boards of Raspberry PI and Arduino, it is more important to fulfil the interests of the project and look over the cost expenditure, especially when your device will be in bulk. 

Likewise, it’s also important to know what your IoT device is capable of, value for cost, performance constraints, the number of sensors or actuators used, mode of connectivity like wired or wireless according to the IoT model’s requirement using technologies like Wi-Fi modules, Bluetooth modules, BLE, 4G LTE etc…

Applications IoT Using Raspberry PI

For Beginners:-

  • Making Printer Wireless.
  • Controlling and instructing Raspberry PI from the web.
  • Building the Smart Home IoT model.
  • Body Temperature Monitoring using PI.
  • Patterned Control of LED bulbs.
  • Creating a Fire Detection System using PI.

Summary

hence, This way a powerful microcomputer like Raspberry PI can be used in the Internet of Things for high processing-based systems.
