Abstract

The invention discloses a sunshine sensor, which comprises a light shading plate comprising a sun-receiving surface and a backlight surface; and a photovoltaic conversion circuit, which comprises first photoresistors arranged on the sun-receiving surface of the light shading plate and used for sensing the light radiation of the sun-receiving surface of the light shading plate, and second photoresistors arranged on the backlight surface of the light shading plate and used for sensing the light radiation of the backlight surface of the light shading plate. The invention also discloses a sunshine measuring device comprising the sunshine sensor. The sunshine sensor senses light radiation through the photoresistors, and the sunshine measuring device realizes sunlight detection according to the illumination intensity difference of the sun-receiving surface and the backlight surface, so that compared with a conventional dark-tube sunshine recorder, the sunshine sensor and the sunshine measuring device can improve measurement accuracy of sunshine duration, realize high-precision automatic observation and can be applied to construct a weather internet of things.

Description

technical field [0001] The invention relates to the technical field of sunshine measurement, in particular to a sunshine sensor and a sunshine measurement device. Background technique [0002] Sunshine is the most intuitive expression of solar radiation. The number of sunshine hours refers to the number of hours the sun actually shines on a place, which is defined as the direct solar radiation intensity reaching or exceeding 120W / m 3 The sum of that time, in hours. The distribution of sunshine hours has important practical significance for the rational layout of agricultural production, planning of urban construction, development of tourism resources, and design of solar power stations. [0003] At present, my country's meteorological department mainly uses the dark tube sunshine meter to measure the sunshine hours. The main principle is as follows: the upper end of the dark tube sunshine meter is closed at the bottom of the cylinder. Small holes, the sunlight enters throug...
