IOT Based Smart Inventory Management System for Kitchen

Abstract

This project presents the design and implementation of a smart kitchen monitoring system that automates the tracking of grocery stock levels and water tank levels. The system uses load cells paired with HX711 amplifiers to measure the weight of groceries stored in containers. An ESP32 microcontroller processes sensor data and sends real-time updates to a mobile application using Wi- Fi and the Blynk IoT platform. Additionally, a GSM module is integrated to send SMS alerts to the user when stock levels are low, ensuring timely replenishment. The water level in the tank is monitored using probes that detect when water reaches specific heights. This information is displayed using LEDs and shared via the mobile app. The entire system is powered using a 230V AC supply converted to 12V and 5V as needed for different components. Programming is done using the Arduino IDE, making the system easily modifiable and scalable. This project demonstrates a reliable, low-cost solution to automate kitchen inventory and water level monitoring, reducing manual effort and increasing convenience through IoT-based smart notifications.
