This project aims to develop a solar intensity sensor device, specifically an electronic circuit based on a photodiode as a sensor, which has been tested to define its linearity in relation to a reference photovoltaic panel, in addition to tests to define transfer functions. Two similar circuits were developed and tested with the only difference existing in the operational amplifier used, and these sensor circuits aim to be low-cost and easy-to-use devices, not requiring specialized labor, neither a big meteorological installation to support it. These devices were developed with a base photodiode and a posterior amplifier circuit for linear amplification of the diode current, thus making it an economical and sensibly reliable sensor for application in various activities that require the sensing of the intensity of solar irradiance, focusing on this work the application related to renewable energy matrices such as solar energy. Finally, two studies were carried out to verify its linearity and sensitive precision, so it was found that one of the sensors under study obtained its viability in the possible replacement of reference photovoltaic plates used in solar plants, and despite the use of the same device in applications where a pyranometer would be underutilized equipment, in addition to its use for applications in academic studies and the maker community.
