Mobile sensing platform for non-ionizing radiation measurement

Abstract

We present an intuitive approach for non-ionizing radiation measurement using smart phone and external sensor. This paper exploits the use of current day technology to monitor the quality of life parameters and bring real time levels of radiation due to mobile communications in atmosphere to USER's smart phone. Electromagnetic radiation comprises of both electric (E) and magnetic field (H) components. By using the relation between free space intrinsic impedance, E and H it is evident that by measuring either electric field strength or magnetic field strength we can measure the power density at any specific location. Using this information an electromagnetically shielded system is developed to measure the electric field strength due to RF signal and power density is computed. The power density is transmitted to the embedded universal asynchronous receiver and transmitter (UART) connected to low power mode Bluetooth module. A smart phone using android operating system is programmed and used to receive the information from external sensor. Thus a mobile sensing platform (MSP) is developed to sense, learn, and interpret the environmental conditions. This work promotes the idea of environmentalism.
