A UVC disinfection system that may include a UVC radiation illumination unit, a control unit, and a node. The node may include (i) a power supply, (ii) a UVC dose sensing unit that comprises a UVC sensing element, wherein the UVC dose sensing unit is configured to sense that the UVC radiation dose received by the node reached a predefined UVC radiation dose; and (iii) a node transmitter that is configured transmit a node unique signal following a sensing, by the UVC dose sensing unit, that the UVC radiation dose received by the node reached a predefined UVC radiation dose. The control unit is configured to control an emission of UVC radiation from the UVC radiation illumination unit based on a reception or a lack of reception of the node unique signal.

Ultraviolet C (UVC) detection

A UV radiation sensor that includes an area that is filled with a dielectric material, the area comprises a first portion of a first thickness and a second trench portion with dielectric of a second thickness, wherein the first thickness is smaller than the second thickness; a floating gate that comprises a first floating gate portion that is positioned above the first area portion and a second floating gate portion that is positioned above the trench portion, wherein the second floating gate portion comprises multiple segments, wherein there are one or more gaps between two or more of the multiple segments; a charging element for charging the floating gate; and a readout element for reading the floating gate.
