Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the embodiments, so that those skilled in the art can implement it with reference to the description.

[0017] This case involves a mixed sintered substance containing simple substance and metal compound, which is a photosensitive material used to manufacture photosensitive sensor probes, and its resistance value can change with the intensity of ultraviolet rays. In particular, the resistance value of the sintered product can decrease linearly with the increase of the intensity of ultraviolet radiation, so the sintered product makes the relationship between the change of the ultraviolet intensity and the resistance value controllable, and is suitable for making photosensitive devices suitable for smart homes. The best choice for sensor probes.

[0018] The sintered product is formed by mixing and sintering the following materials in parts by weight:

Abstract

The disclosure discloses a photosensitive material for a sensor, wherein the resistance value of the photosensitive material is reduced linearly with increasing of the intensity of ultraviolet irradiation. The photosensitive material is prepared by the following materials, by weight, based on mixing and sintering: 1 to 3 parts of tantalum, 18 to 20 parts of cadmium sulfide, 2 to 4 parts of selenium powder, 10 to 12 parts of aluminum sulfide, 2 to 4 parts of nickel powder, 6 to 8 parts of bismuth sulfide, 1 to 3 parts of titanium powder, 10 to 12 parts of europium oxide, 1 to 3 parts of ruthenium, 6 to 8 parts of germanium oxide, 5 to 7 parts of silicon powder, and 3 to 5 parts of osmium oxide. The invention provides a novel mixed sintered material for a photosensitive sensor probe; and the resistance value of the material is reduced linearly with increasing of the intensity of ultraviolet irradiation. And the material has high sensitivity and quick response. Besides, the material has advantages of high stability, good aging-resistant and high-temperature-resistant performances, low cost, and simple manufacturing process.

Description

technical field [0001] The invention relates to a photosensitive material, in particular to a material for preparing a photoresistor in a sensor, in particular to a photoresistor material for monitoring the intensity of ultraviolet rays in a smart home system. Background technique [0002] In recent years, with the rapid development of Internet technology, smart home system devices have begun to rise slowly. This smart home system is mainly used for remote monitoring and remote command of people and various living facilities at home. For example, the heartbeat, pulse and other information of the elderly can be monitored through the ECG sensor; the body temperature of the elderly or children can be sensed through the thermal sensor , and can also control the temperature of the central air conditioner in the home; for example, the windows can be selectively opened and closed by detecting the intensity of outdoor ultraviolet rays. And if you want to realize this function, you ...
