FIELD: physics.
SUBSTANCE: invention relates to an electrostatic field sensor and a safety system in inner spaces, which can measure electrostatic fields and their variations along a metal conductor which acts as a detecting element or antenna (1). Sensitive element is connected to electronic circuit (2, 3, 4, 31, 32) configured to decode said electrostatic field changes around conductor and detect very small changes in electrostatic field using processor (7), providing the possibility of detecting the presence of a person on the territory surrounding antenna (1), and differentiating between the presence of a human and any other type of animal or object.
EFFECT: electrostatic field sensor and safety system in inner and outer space are disclosed.
