This presentation contains explanation regarding photosensitive device, precision sensor, sensor, and accuracy. There are lots of information around comparison, light sensor, and photovoltaic are explained in this presentation.
In the presentation we can get things around capacity, error, photoresistors, and precision. The following are some excerpt from this presentation:
Why track the Sun? The performance of a photovoltaic application depends essentially on the amount of solar energy captured by the cells. Dual-axis tracking systems can improve the amount of energy collected in about 40% when compared to static systems. Fig.1: Comparison between a dual-axis tracking system and a static one. www.ws-energia.com How to track the Sun? Most Common ways to track the sun are: • The astronomical calendar approach Uses time and geographical coordinates • The light sensor-based approach Uses photo-sensitive devices like: » photoresistors » photodiodes » Phototransistors • Machine vision Uses arrays of photo-sensitive devices like CCD cameras.
Even more, this presentation contains information about photodiode, phototransistor, and the light sensor.
