Welcome to my blog post on the Raspberry Pi Plant Identification Device! In this project, I aimed to leverage advanced object detection technology to identify and monitor plant species in a garden environment. Using a Raspberry Pi 4b, a V2 camera module, TensorFlow Lite, and a Google Coral Accelerator, this device offers an innovative solution for gardeners and plant enthusiasts who wish to keep track of their plants’ health and species.

Overview of the Purpose

The primary purpose of this project was to create a device that can accurately identify various plant species using real-time image processing and machine learning. By employing the Raspberry Pi and Google Coral Accelerator, I intended to enhance the processing power and speed of the identification process. The ultimate goal was to develop a practical tool that can assist gardeners in maintaining and monitoring their plants more effectively.
