التحكم الذاتي لفرن الميكروويف بناء على قياس قدرة الموجات الدقيقة

Abstract EN

Domestic microwave ovens do not contain features for detecting material state inside the oven.

the state change or lack in material required automatic switch off the microwave oven to overtake the overheating and oven damage.

Hence, this research aims to provide a new concept for automatic control the microwave oven based on measurement of microwave power leaked to outside of oven.

In this research the microwave oven was linked to a spectrum analyzer and computer via physical media and computer programs.

The microwave oven circuit was developed to accommodate the new automatic control system.

Computer code was prepared to read the measured energy and automatically switch off the microwave oven.

The experiments repeatition confirmed the results with a percentage of error of about (5.7%).

The results showed the success of the new concept that confirmed the possibility of automatic control of the microwave oven based on leakage measurement of the microwave power that changes according to the material state inside the microwave oven
