Abstract: Provided is a measuring device for measuring a distance between the measuring device and a user. The measuring device includes a distance sensor configured to generate a distance signal indicative of the distance, an IR radiation sensor configured to generate a temperature signal indicative of the IR radiation emitted by the user, and a control unit. The control unit is configured to: in a calibration mode, acquire the distance signal and the temperature signal respectively through the distance sensor and the IR radiation sensor and, on the basis of the distance signal and the temperature signal, generate a calibration curve which associates to each other values of the temperature signal with respective value of the distance; and in a calibrated mode, acquire the temperature signal through the IR radiation sensor and, on the basis of the temperature signal and the calibration curve, determine the distance.

Abstract: The present disclosure is directed to a device for detecting the passage of an infrared, IR, radiation emitting body in a monitoring zone. The device has a first surface and a second surface mutually tilted and configured to face the monitoring zone. The device includes a first IR radiation sensor extending on the first surface and a second IR radiation sensor extending on the second surface. The first IR radiation sensor is configured to detect the IR radiation of the emitting body when the emitting body is in a first field of view of the first IR radiation sensor and the second IR radiation sensor is configured to detect the IR radiation of the emitting body when the emitting body is in a second field of view of the second IR radiation sensor. The first and the second fields of views are configured to be partially superimposed on each other at the monitoring zone.
