Spatial and temporal monitoring of electromagnetic fields (EMFs) is a priority of the World Health Organisation’s (WHO) 
research agenda. People are worried about health effects of radiofrequency (RF) radiation of base stations (e.g., from 5G 
technology) and of extreme low frequency (ELF) fields of high tension lines. Governments and operators (mobile 
operators, electricity distributors) need to monitor fields for risk communication, policy, and satisfying scientific and 
regional/national norms. In this project, we will design a universal low-cost electromagnetic field EMF sensor consisting 
of a modular combined sensor approach to measure both ELF and RF fields. This unique sensor will enable governments 
and operators to monitor radiation in an all-encompassing way. Moreover, we will realize real-time environmental EMF 
exposure mapping and optimal sensor placement algorithms.
