Description
CDG-11B Pyranometer Sensor
The CDG-11B precision solar pyranometer sensor based on the thermopile principle. It make the sensing elements by winding – plated thermopiles with multi contacts. We coat its surface with a black coating that has a high absorption rate.
Hot contacts on the pyranometer surface, while the cold junction is located within the body, temperature difference between the hot and cold junction generates electromotive force, the thermoelectric effect is proportional to the solar radiation. In order to reduce the ambient temperature effect, temperature compensation circuit designed here to reduce the effects to products properties.

Application
Photovoltaic system：
◉Accurately measure the amount of solar radiation reaching solar panels to help determine the best location for solar power plants, as well as assess the potential of solar resources in different regions, and provide data support for the planning and construction of large-scale solar power plants.
◉By monitoring precision pyranometer sensor intensity in real – time, we can quickly detect if solar panels are blocked by dust, debris, or have malfunctioned, enabling timely cleaning and maintenance. Additionally, it helps adjust the panels’ angle and direction to maintain an optimal orientation to sunlight, enhancing power – generation efficiency and energy output.
Climatic study:
◉Measuring solar radiation absorbed and reflected by Earth’s surface helps scientists understand Earth’s energy budget, study solar radiation’s role in climate change and the Earth system’s response to it. This is crucial for predicting climate change trends and formulating strategies.
◉Combined with other meteorological data, the relationship between solar radiation and climate factors (like temperature and precipitation) was analyzed. The absorption and scattering of solar radiation by greenhouse gases, and their impacts on the Earth’s climate system were studied, to reference the evaluation of greenhouse gas emission reduction effects.
Agricultural field:
◉Measure the solar radiation intensity in the field. This helps farmers understand the light conditions during crop growth. Based on the different light requirements of various crops, they can adjust planting density, plant spacing, etc., to improve the crops’ light environment, enhance their photosynthesis efficiency, and boost crop growth and development.
◉The intensity of solar radiation affects soil water evaporation and transpiration of crops, and by monitoring solar radiation, combined with soil moisture and meteorological data, farmers can make more accurate irrigation plans.
