The Raspberry Pi is an amazing little computer for the price. Now that you have a Raspberry Pi lets put it to work!
Previously, I’ve talked about using an old Powerspec PC as my home automation server. An outdated PC works fine as a server in some cases, but really, running a little spaceheater-ish P4 around the clock? That’s so 2006. It would be kind of silly to blog all about power efficient lightbulbs and realtime energy monitoring while having a 10 year old PC burning 400 watts all the time. And who wants to run all their home automation stuff on Windows, anyway?
Over the last year, I’ve moved almost all my home automation code and programs over to a new platform: the Raspberry Pi. The PI makes a ton of sense as an HA server. It’s tiny, cheap, extremely power efficient, and can run a full Linux operating system with a graphical interface. You can tie it into low-level sensors (sort of), but at the same time, it can run Python scripts faster than the old Powerspec.
Here’s a little video introducing my Raspberry Pi home automation server:
Another great thing about the Raspberry Pi is that you can easily get it onto wifi. Just add an external adapter like the cheapo ones from Rosewill and you’re set. You can put your server anywhere in the house–in a cabinet, under your desk, in the garage, etc. Here’s my wifi setup:
So once you have your Raspberry Pi home automation server set up (and perhaps embedded in a project), how do you actually communicate it or upload new code? You can be fancy and get it to run an FTP server, but I find it’s often easier just to use Putty to send stuff over SSH:
So what does my server actually do? Well for starters, it uses CHRON to run my Bidgely scraping script once per minute, pulling in my realtime electrical usage. It also scrapes data from the endpoints of a ton of other APIs. You can even have it control things like Phillips Hue over your home network, using Python. I’ll share more on how I’m using my Pi in future posts.

The blend of Artificial intelligence (AI) and the Internet of Things (IoT) are opening new business frontiers. With technological achievements such as the Raspberry Pi computing models, we are witnessing significant expansion in AI potential for businesses. From automated video analytics to AI-infused assistants, AI development with Raspberry Pi 4 is heralding breakthrough applications across verticles. Let’s deeply analyze how Raspberry Pi 4 is providing for a great catalyst for artificial intelligence services to build dynamic applications.
Unlocking the Features of Raspberry Pi 4
The release of the Raspberry Pi series of single-board computers has completely revolutionized the software development space. After the remarkable performance of Raspberry Pi Zero and its successors, Raspberry Pi 4 has hit the market with improved architecture.
ai development with raspberry pi 4
The Raspberry Pi 4 Model B is the latest version in the cost-effective Raspberry Pi mini-computer series.
The Raspberry Pi 4 SoC witnessed an upgrade from Cortex A53 chips to a Cortex A 72 SoC which is a major performance booster supported by a USB 3.0 port. The system is powered by 4 GB RAM with dual 4k display output at 30fps, making it a strong replacement of a viable home theatre setting. With a pre-installed Linux-based OS called NOOBS, Pi 4 is poised to accelerate the development of the following applications-
a) Video streaming and creation of stop motion movies
b) Smart Surveillance models
c) Home Automation systems
d) Retro Gaming machines, and more
However, the most disruptive applications of Raspberry Pi 4 comes with machine learning. From chatbots to object detection, AI development with Raspberry Pi 4 expands the horizons of machine learning development services across businesses. Let’s explore some of these.
IoT Applications and AI Development with Raspberry Pi 4
Though previous Raspberry Pi series ran cloud-based image processing models, Pi 4’s 64-bit quad-core processor can also train AI models at the edge efficiently. However, in the face of memory and compute restraints, it is advisable to use a cloud’s computational powers to deploy ML models such as-
a) Image Classification
Assigning specific labels to the image or video frame. The application requires coding the Raspberry Pi’s camera to capture images and record videos. Image labeling is emerging as an effective automation tool to monitor workplace activities, manufacturing cycles, and construction sites.
b) Object Detection
Recognizing objects by creating bounding boxes in an image. It requires trained datasets to run image processing operations on Raspberry Pi using its GPU. Object detection models enable retail, warehousing, and security businesses to automate critical operations effectively.
c) Video Analytics
By installing open-source libraries like TensorFlow on Raspberry Pi, businesses can train deep video analytics models for several use cases. At Oodles, we practiced AI development with Raspberry Pi to build a real-time environment monitoring systems for party lounge.
We have achieved over 80% accuracy in detecting image anomalies and extracting actionable insights from video frames. We used a well-trained OpenCV library on Raspberry Pi to inform party-goers about live music streaming status across the image processing, video analytics, and NLP-based chatbotslisted lounges.
Raspberry Pi’s compact architecture has accelerated the development of social media and voice-based assistant bots. A Python-based code on the Pi and an active Twitter account are the pre-requisites for creating a Twitter bot that
a) Automates business interactions and engages online users
b) Augments upselling efforts by pitching relevant business services to the target audience
c) Enhances customer experience with accurate and quick responses
For AI assistants, businesses can use cloud-based Google SDKs to run voice-controlled assistant on the Pi. From home automation systems to routine user queries, AI development with Raspberry Pi 4 can be used for dynamic applications.
