RAG stands for Retrieval Augmented Generation. It enhances the large language models (LLMs) by integrating them with external data sources. This allows LLMs to generate more accurate and relevant responses by providing it with information from databases or knowledge bases, rather than relying on their pre-trained data.

In this post, You will understand how to collect values from an Arduino with a connected Raspberry PI over a serial port. This can be useful if you want collect sensor values over a period of time and store them on a timeseries database or trigger an alert either from the Raspberry PI (email notification or telegram alert) or from the Arduino (like fire alerting systems). Let's dive in!
