Development of Wireless Electric Field Mill for Atmospheric Electric Field Observation

TELKOMNIKA (Telecommunication Computing Electronics and Control), 2014
Rotating-vane electric field mill (REFM) sensor is one of the popular methods to measure atmospheric quasi-static electric field. Lightning incident occasion can be predicted by observing electric fields strength in atmosphere. In this paper an integration of REFM with an online wireless data monitoring system for long distance observation and data ...
