In this thesis, we use eBox2300 hardware platform and Windows CE operating system for monitoring the solar power system. The data of temperature and voltage collected by sensing devices are transferred back to the monitoring system through eBox2300’s I/O interface. The monitor system displays the voltage and temperature data in the screen and the data will be stored into Access database automatically. The data stored in the database can be analyzed to achieve the goal of monitor. The eBox2300 provides networking ability for remote monitor/control. Through the network or Internet we can know the eBox2300’s condition and do something when the system is out of order.
