Development of Sensor Module for Detecting the Magnetron Power Based on Microwave Oven Frequency

This study presents the design of sensor module to be used in analyzing the electromagnetic power created from magnetron by using microwave as the case study on basis of Rectenna (Rectifying antenna) consisting of 2 main parts including sensing part and transduction part. On part of sensing part, the design would be made on the basic principle of monopole antenna; on part of transduction part, the design would be made on the basis of rectifier circuit, to function in converting the electromagnetic power received from magnetron to be in form of DC current, here the Hall Effect Sensor that was installed inside the current sensor module was used as the measuring equipment, with Arduino UNO R3 as the controller for recording electrical current including temperature. The experimental results would be used to analyze the appropriate form of sensor module. This research compared sensor module for 3 forms including Type A, Type B, and Type C, with different sizes of diameter of wires consisting, by comparing the efficiency in preventing the leak of measured power. According to the test of sensor modules in 3 forms on the same condition, it was found that the means of electrical current from converting the electromagnetic power of microwave.
