Resumo: Concerns regarding long-term effects of stray electromagnetic fields emitted by household appliances have been usually covered by mainstream and social media outlets, even though biomedical exposure studies have conclusions leaning towards low-risks. The quick deployment of Internet of Things (IoT) shows that the number of connected devices is likely to increase even more. Though most systems operate with very low-amplitude field levels, the coexistence of several different devices and continuous operation near the human body is seen as a possible cause of illnesses, particularly in children. This study shows a method of addressing fields at the 2450-MHz range using low-cost and easily constructed devices, based on a software-defined radio operating as a receiver. It allows the investigation of hot spots inside residential or office areas, with measured amplitude field levels found after proper conversion using the sensor antenna factor.
