Automated Grocery Monitoring System for Elderly People

Abstract: The Automated Grocery Monitoring System for Elderly People is an IoT-based solution developed using the ESP32 microcontroller to intelligently manage household grocery inventory and enhance kitchen efficiency. The system continuously monitors the weight of two essential grocery containers using load cells, while also tracking environmental parameters such as temperature and humidity through the DHT11 sensor, and food spoilage gases using an MQ2 gas sensor. Real-time data is displayed on an LCD screen and communicated via Telegram, allowing users to receive instant updates on grocery availability, environmental conditions, and potential spoilage alerts. When the weight of an item falls below a predefined threshold or spoilage is detected, the system sends an automatic notification to prompt refilling or replacement. Furthermore, based on the available grocery items, the system provides intelligent recipe recommendations, helping users plan meals effectively. This smart Ordering approach reduces food waste, ensures timely grocery management, and introduces a personalized cooking assistant feature, all integrated through a user-friendly Telegram interface.
