Permanent and transitory systems are included. Full-time dataloggers are needed for the acquisition, storage, and transfer of measurement data. Low power single board computers applicable to more complex calculations, processes, and protocols are discussed. Measurements of power consumption for selected laptop computers are presented to allow users to make informed choices in this common tool used during field trips.
Laptop Power ConsumptionComputer technology plays a big part in polar research, however choosing a system that can complete the task while using the least power is important. Below is power consumption data for candidate laptops in various operational modes. Clicking on the laptop name will display a graph of its power usage in different modes of operation.

Low Power Single Board Computer
The Technologics TS-7260 single board computer (SBC) is a very low power computer board with a high degree of functionality. The board consumes less than 1 Watt at full 200 MHz processor speed. Power consumption can drop to 0.25 Watts at slower clock speeds. The ARM-based processor runs Linux. The board supports Ethernet, USB, serial, and analog and digital I/O. It has been used successfully on several projects by SRI International. Please check back for more information or contact Roy Stehle via the link on the Contacts page.
