Data Logger

This device has 4 input channels and can be configured through a Visual Basic application. The data from the input channels is saved in a 2k external EEPROM memory from Atmel. Every sample that is stored in the EEPROM memory is saved with the time at which the sample has been made. After the configuration of the device the user can see the results through a chart in the VB application.
The image below represents the fundamental schematic of the data logger and then the Visual Basic application.
