Rf Leakage Detection System for Microwave Based Industrial Heating Appliances

According to WHO standard the RF leakage beyond +10 dBm are hazardous to human being. The microwave oven is a kitchen appliance which is used in day to day life. But, until 1967 an affordable and compact microwave oven was not readily available for domestic use. The obvious cooking advantages provided by the microwave oven ensured that its uptake would be rapid. It is extensive with up to 90 percent of the western world’s households currently owning one. After long use of oven there is leakage of microwave radiations takes place. Microwave leakage can easily cross +10 dBm powers. Public concern over leakage from the microwave ovens was present from the very beginning. Many people believing that radiation leakage was similar to atomic radiation that could lead to serious health problems, including cancer. These radiations are hazardous to human being. Number of people use microwave ovens every year and make them vulnerable to risk. Effort has been taken to design the system which detects the leaked radiations using microstrip antenna. Designed RF circuit amplifies detects radiations. Raspberry pi checks those leaked radiations for the threshold value. If these radiations are found above the threshold value, then using GSM the system informs to their respective owner and manufacturer about leakage. So they can take appropriate action regarding the issue.
