Light Dependence Resistor Used as a Sensor for a Solar Tracker
This research focuses on a sensor that is suitable for solar tracking. In tracking system, solar panel harvests energyoptimally if the panel surface position is perpendicular to the light direction. To constructs mechatronic system, theselection of sensor is very important. Datasheet is helpful for pre selection. Further research has been carried out todetermine the specific sensor which will be mounted into electronic circuit. Based on the experiment on selectedsensor, sensor characteristic is obtained in detail. Sensor output is processed in the microprocessor. At the end, anactuator has a task to swap desired mechanical movement which is instructed by controller. Actuator must fulfilltechnical requirements, such as load, speed, durability, price, availability and maintenance aspect. This papergives an overview to answer this problem.
