However, many ultraviolet sensors directly expose the photosensitive layer to the photosensitive layer. In the external environment, this will not only make the component characteristics of the photosensitive layer itself susceptible to environmental factors such as external temperature, humidity, oxygen and ozone, but also shorten the service life of the ultraviolet sensor. However, the impedance type ultraviolet sensor uses the impedance change of the photosensitive layer to measure the ultraviolet light I of the light source, but the ultraviolet sensing m on the market currently cannot effectively improve the sensor itself. Interference such as visible light, infrared light and moisture interference. In addition, although the target month;) some ultraviolet sensors on the market have been changed in order to prevent the component characteristics of the photosensitive layer itself from being affected by external environmental factors, so a protective layer is disposed on the photosensitive layer, but such ultraviolet sensing The protective layer is disposed on the photosensitive layer in a packaged manner to achieve the protection (4). However, the procedure of such a sealed process is complicated and complicated, thereby causing inconvenience in manufacturing the ultraviolet sensor. The cost is also high. The 'sensing & volume is also increased' to cause obstacles in use. The main purpose of this is to provide a UV sensor with a light-transmissive 1312408 layer, which is used as a protective layer for the ultraviolet light-sensitive layer of the sensor. ~ "° Another object of the present invention is to provide an ultraviolet sensor which increases the contact area between the ultraviolet photosensitive layer and the first and second electrode layers by the first 'second electrode layer of the comb structure 'To improve the sensitivity of the sensor itself: the change of the impedance of the ultraviolet photosensitive layer. ' Another object of the present invention is to provide an ultraviolet sensor which provides a protective layer directly covering the ultraviolet photosensitive layer and the first and the first The upper layer of the second layer is used as the protective layer of the ultraviolet photosensitive layer of the „Xuan sensor. ...° The technical means for solving the problem of the present invention: The technical means adopted by the present invention for solving the problems of the prior art are for supplying ultraviolet light The structure of the sensor is that the surface of the substrate body has an ultraviolet light-sensitive layer, a first electrode layer and a second electrode layer, and the outer photosensitive layer is for receiving ultraviolet rays from the outside, and the first electrode The layer core electrode layer is a corresponding comb-like structure, and a surface of the ultraviolet ray layer and the second electrode layer is further formed with a transparent layer as a protective layer of the ultraviolet ray photosensitive layer. Application In an embodiment, the first electrode layer and the second electrode: = between the substrate body and the ultraviolet photosensitive layer, and between the protective layers may be located between the photosensitive layer of the substrate and the ultraviolet photosensitive layer, respectively The light transmission guarantees the efficacy of the prior art: Compared with the prior art, the ultraviolet sensor of the present invention uses a light-transmitting protective layer as a protective layer of the ultraviolet photosensitive layer to avoid the ultraviolet rays. The photosensitive layer changes its own component characteristics due to external environmental factors, and increases the service life of the ultraviolet sensor, and the light-transmissive protective layer is formed by a simple coating method compared with the conventional technology. Therefore, the operating procedure of the process can be simplified. Further, the present invention utilizes the first 'second electrode layer of the comb structure to increase the contact area with the ultraviolet photosensitive layer to improve the sensitivity of the sensor itself to the ultraviolet light. The sensitivity of the layer impedance variation, thus exhibiting the excellent commercial added value of the present invention. The specific embodiment adopted by the present disclosure will be exemplified by the following examples and FIG formula of the form described further. [Embodiment
