Abstract :
In this paper a sun tracking system is presented. The main component of this system is a solar sensor. It is a light source position sensor. The sensor is made using MEMS technology to increase the sensitivity of the sensor and reduce manufacture cost. An algorithm is also designed to implement the control system considering all the different meteorological conditions. Two scale models has been made to test the complete system, that is, as much as the sensor as the algorithm. The scale models are based in real applications where the sensor can be incorporated, as they are heliostats and photovoltaic cells. The experimental results are successful and show the robustness and high precision of the system
