This thesis explores the design and construction of check leakage of microwaves to fix the leakage of microwaves from the microwave. This project aims to generation applications. Microcontrollers Tech's best detector circuits to the dipole. The machine uses dipole frequency 2.45 GHz receive microwave plugged into a circuit-tech sector to a techno signal antenna receives a voltage and voltage to pin analog control circuit to display. the measured values to the LCD screen, the value of the measurement will inform the measures that are microwave leaked it to sound an alarm when the microwave sensor is in danger. and to disable the microwave oven immediately. The machine can measure the leakage of the microwave according to the standards.
