Abstract

The main aim of this project is to develop a smart oven system that has the capability to control the temperature and duration of cooking automatically according to the size and weight of the food. In this proposed system, a microcontroller NodeMCU ESP8266 was used as core component of the system. All data will be controlled based on the programming code written in Arduino IDE. The Graphical user interface was developed using MIT app inventor. This will allow the user to control the oven system using a smartphone or tablet through Wi-Fi. The proposed system was implemented to enhance the existing system. This was archived by using a food probe sensor to get the internal temperature of the food and by integrating the system with IoT. The performance of the developed system is evaluated by testing the weight of the food using loadcell, the ambient temperature of the oven, cooking duration of different weights of chicken part, Cooking Duration of different weights, and doneness level for beef, Food probe sensor to be tested with different power supply, and IOT platform latency. The proposed system has 95% accuracy in terms of monitoring the temperature of the oven, while the existing system is only 89%. The proposed system was also able to estimate the duration for cooking depending on the weight of food inserted into the oven. The whole chicken was estimated to take 45 minutes where the weight of the whole chicken is 1kg. On the other hand, the thighs which have 100 grams was estimated to have 25 minutes. The estimating time was estimated by knowing the weight of the food. Further enhancement can be made to the system one of these recommendations is to involve image processing technique in the system.
