Non-contact Human Proximity Sensor

The paper describes a non-contact human proximity sensor. The relevance of this device in the conditions of coronovirus is high, as it allows you to touch open surfaces with your hands less. The aim of the work is to study a capacitive non-contact sensor, which reacts to the approach of a person in it. The result of the work is the development of a circuit of a non-contact sensor. The main components of this circuit by passive elements are logical elements. Also considered the advantages and disadvantages of a non-contact proximity sensor.
