Natural lightning strikes sometimes are the main cause of fires, industrial accidents, injuries, and even death. In this paper, the novel electrostatic field sensor was introduced and its basic feature was quantitatively investigated based on performance on a laboratory scale. The quadrilateral metal plate was used and assumed as the cloud which was attached to a HV DC power source to control its charge level. As for the results, the applied voltage had a positive correlation to the detection signal while distance did not have an effect on the overall electrostatic field values which confirmed the reliability of this novel sensor.
