Data Logger Overview
This Data Logger was a custom data logger designed
under contract and described here for reference purposes. Please contact
us to describe your requirements for a custom data logging solution.
The Data Logger tracks the date and time of any electrical event. It
is only 1" by 1" in size, has a battery life of three years, a memory of 10,000
events, and can monitor the activity of an infinite
variety of devices.


Data Logger Output
Data is extracted from the data logger using another unit called the
Collector, which can upload the data to a computer. Click on the figure
below to view the spreadsheet application that communicates with the Collector.

Once the data is uploaded, it can be graphed automatically, as the figure

Example Application
The Data Logger is being used by the Light Up The World Foundation to
collect solid-state lamp usage throughout developing nations world-wide. The
following figure shows the lamp/logger connection.

The Data Logger is the ideal device for this application as it is designed
to operate in the harshest environmental conditions, from the dust and heat of
the desert to the humidity and moisture of the rainforest to the cold of the
remotest Himalaya.
