Nowadays the growing microwave environmental contamination including home space can become a real challenge to all the residents. We present new portable devices, which provide a continuous remote monitoring of the microwave home background. These three different designs allow monitoring four main human microwave safety characteristics: SA - specific absorbed energy; MPE - maximum permissible exposure; SAR - specific absorption rate, and PD - power density. One may set a specific alarm level to match it with individual microwave sensitivity for personal precaution. New microwave dosimeters may work in professional, occupational and personal modes in smart home applications.
