Sun Spot (Sun Small Programmable Object Technology) is a wireless sensor network (WSN) mote developed by Sun Microsystems. The device is built upon the IEEE 802.15.4 standard. Unlike other available mote systems, the Sun SPOT is built on the Java 2 Micro Edition Virtual Machine (JVM).

The Sun SPOT project explores wireless transducer technologies that enable the emerging network of things. We are building a hardware and software research platform to overcome the challenges that currently inhibit development of tiny sensing devices.

Automatic Sun Tracking System (ASTS)


INTRODUCTION:

In remote areas the sun is a cheap source of electricity because instead of hydraulic generators it uses solar cells to produce electricity. While the output of solar cells depends on the intensity of sunlight and the angle of incidence. It means to get maximum efficiency; the solar panels1 must remain in front of sun during the whole day. But due to rotation of earth those panels canâ„¢t maintain their position always in front ....etc

ABSTRACT
Wind from the Sun is a new technology for obtaining power from the sun and wind. This hybrid system turns the sun's light into heat, then uses that heat to create a wind within a horizontal large-diameter pipe. The wind inside the pipe is converted into electric power using a series of wind turbines.
1. The Collector: A large area of land is covered with a material with low reflectivity (dark in color). This material converts the sun's light into heat.
2. Heating the air: The collector increa ....etc

By default a Solar Panel moves from east to west from morning to evening. The problem arises when there is a cloud over the panel interrupting the light. The current system continuously monitors the position of the cloud using Light Dependent Resistor. An interrupt is sent to the micro controller from the device as soon as the cloud covers the panel. The panel then starts rotating in the east and west direction in search of light. Once the light is detected the panel stops at that position and continues its normal operation. The input is fed as ....etc

In nature, it is solar power that creates wind power. Consider the example of the sea breeze. The sun heats both land and sea, but the land heats up more quickly and reaches a higher temperature than the sea. The air over the land becomes hotter than the air over the sea and the hot air rises, creating an area of lower air pressure (close to the surface). Air moves from the area of higher pressure over the sea to the area of lower pressure over the land. The cool sea air heats up as it moves over the land and so it rises, creating a cycle. The ....etc
