摘要

Solar sensor and method to detect the position of the sun with respect to its transverse axis. The invention consists of a solar sensor with a matrix of pixels that measure the luminous intensity. The reading of the pixels is asynchronous and based on the communication protocol Address Event Representation. The pixels send asynchronously to the outside events with a frequency proportional to the luminous intensity. Each pixel can, at most, fire once after an initial reset (Time-to-first-spike). The AER communication logic is modified to allow a maximum programmable number of pixels that fire. The calculation of the position of the Sun is made by means of a digital block of computation that determines the centroid of the most illuminated pixels and that are the only ones that send information. The scientific-technical area of the invention is that of physical technologies, specifically microelectronics.
