An Internet of Things (IoT)-based Approach for Real-Time Kitchen Monitoring Using NodeMCU 1.0

Monitoring the kitchen is one thing everyone should consider as it is the most probable place in the house where accidents tend to happen. This paper explores the idea of building an automated kitchen monitoring system using Internet of Things (IoT) and microcontroller-based sensors. An IoT approach for monitoring the kitchen is encouraged due to the fact that the number of Internet users has increased exponentially in recent years by technological advancements in the field of telecommunication and also increased the standard of living of people. This automated kitchen monitoring system has sensor unit (to monitor the kitchen parameters) which is interfaced to a microcontroller development board (Arduino UNO), and the transmission of this parameter values through Internet is carried out by NodeMCU 1.0. The system comes with a user-friendly mobile application to monitor kitchen parameters like temperature (in degree Celsius), percentage of humidity, potential LPG gas leakage, accidental kitchen fires and weight scale for groceries. The mobile application is developed using an online tool MIT APP inventor and the database which stores the kitchen parameters temporarily is Google’s Firebase Database. Additionally, the mobile application also has a feature of controlling two electronic appliances (connected to a two-channel relay) from anywhere around the world.
