A Microcontroller Based Electric Cooker/Oven with Temperature and Time Control for the Developing Countries

摘要

This article presents the development of a novel microcontroller based electric cooker/Oven with time and temperature control. It employs the rich application of ATmega8- microcontroller as the core component. The system is software driven through the C-language code written to the microcontroller. Temperature control is achieved using a temperature sensor (LM35). The sensor monitors and measures the temperature of the system, keeping it at a preset value. The internal timing function of the microcontroller is used to time the cooking, baking or drying process. This whole cycle of temperature and time control is repeated until the set time elapses or until the item being cooked, dried or baked is ready (that is when the time is set to infinity mode). These processes conserve power and essential food nutrients. The cooker/oven is a cutting edge innovation and it is efficient, reliable and user friendly
