Signal Transducers of Sensor Devices on Photovoltaic Power Supply and Optical Communication

Abstract

The analysis of the sensor devices operation principles with photovoltaic power and optical communications have been performed. The functioning of such devices is provided by a modulated light flux. An informative signal that forms a sensor device is a QR code. The formation of a QR code is carried out using micropower displays based on e-ink electronic ink technologies, and this QR code is read by a smartphone camera. The main results of photovoltaic sensor devices development based on optical communications are presented, in particular, the analysis and generalization of operation principles, simulations and signal converters prototyping. Examples of a photo-sensor converters studies with transimpedance amplification and gyrator load are analyzed. A layout of signal converters and examples of oscillograms are presented in the course of the considered photosensor devices signal converters experimental studies.
