+# Smart Retail with reComputerR11 and AI kit
+
+![](../../pictures/Chapter6/smart_retail.png)
+
+This project demonstrates how to use the reComputer R11 and AI Kit to enhance your store, making it smarter and more efficient. 
+
+We retrained the YOLOv8n model to detect Coca-Cola, chips, crackers, crisps, milk, and popcorn. The model is deployed on the AI Kit to monitor the inventory of these items on shelves, notifying store staff when restocking is needed. Additionally, we utilized a pre-trained EfficientNet model to detect people in the warehouse. This model, deployed on the CPU in TFLite format, helps prevent theft by identifying unauthorized intrusions.
+
+Beyond inventory and security, we integrated environmental monitoring using temperature and humidity sensors. A ReSpeaker was added to emit alerts when intrusions are detected, notifying security personnel. Furthermore, we connected fans and lighting through RS485 for convenient operation by staff.
+
+All data and controls are consolidated into a Node-RED dashboard, providing an intuitive interface for monitoring and managing store operations effectively.
