Automatic Sun Tracking System Using PSoC

Bhavesh Pandey, Anita Agrawal

Vast amount of energy is available within the core of sun. The energy that is received from sun in an hour is more than that is consumed by us in a year [1]. If human race is able to capture even 1% of the total energy which sun delivers then we can cater the need of our race for decades. Efforts are continuously being made to capture as much energy as we can in order to store most of the energy which se are getting. In this paper a device called solar tracker has been discussed. Solar panels give maximum output when the plane of the solar collector is normal to incident radiations [2]. The system discussed in this paper uses a PSoC device to control a small model of solar tracker. Voltage across the solar panel and a photoresistor is fed as an input to the PSoC to be processed and the output is fed to the geared DC motor.
