Project Idea:
Develop an IoT-based smart retail shelf monitoring system that tracks product availability, shelf stock levels, and alerts store managers when restocking is needed. This system ensures efficient inventory management, reduces manual shelf audits, and enhances the shopping experience by preventing out-of-stock situations.
Project Description:
The IoT-Based Smart Retail Shelf Monitoring System uses IR sensors placed on shelves to detect product stock levels. A Node MCU ESP32 microcontroller collects sensor data and sends real-time updates to a cloud platform (Blynk). Store managers can monitor stock status on a smartphone dashboard and receive alerts when stock falls below a predefined threshold. This system helps automate inventory checks, improve replenishment cycles, and supports efficient shelf space utilization, making it ideal for smart retail stores and supermarkets.
Components List:
Node MCU ESP32
IR Sensors for count-based tracking.
Power Supply Adapter.
