The invention relates to a UV light sensor produced in a CMOS method, comprising a substrate that has a surface, one or more sensor elements that detect radiation and are designed in said substrate, at least one passivation layer arranged over said substrate surface, and a functional layer that is arranged over said passivation layer and designed in the form of at least one filter. The problem addressed by the invention of providing a UV light sensor which is sensitive exclusively within the UV wavelength range is solved, in terms of arrangement, by means of filters designed directly on a planar passivation layer, and stray light suppressing means around said at least one sensor element and/or around the UV light sensor. In terms of the method, the problem is solved by measuring two output signal from at least two photo diodes fitted with different filters, and by determining a mathematical relationship between the two output signals.

An anti-copy electronic device contains: a wireless signal controller having a sensor, and the wireless signal controller and the sensor are accommodated in a casing. The sensor has humidity detection, pressure detection, lights detection, color temperature detection, ultraviolet (UV) detection, and special gases detection in an interior space of the casing. After the casing is removed, the sensor detects a change of humidity, pressure, lights, color temperature, ultraviolet (UV), and special gases in the interior space and sends an indication signal to the wireless signal controller so that the wireless signal controller destroys a password setting program of the wireless signal controller, thus avoiding copy of the password setting program.
