Student White Paper: Using the MA3 Absolute Shaft Encoder to Determine Wind Direction. Authors Kevin L. and Justin D., Confederation College, Thunder Bay, Ontario, Canada
Abstract: Two electrical engineering students in the computer control program at Confederation College completed their third year project, a remote weather station, utilizing the MA3 miniature absolute encoder to test wind speed and direction on a wind vane. The MA3 was selected due to its small size, analog output of 0 to 5 Volts, and the availability of a ball bearing option to provide little... Read More »
How the T7 Networked Absolute Inclinometer Drives Down the Cost of Solar Energy in Concentrated Solar Power Systems
Abstract: Concentrated solar power (CSP) and concentrated photovoltaic (CPV) methodologies generate electricity by focusing a large amount of sunlight onto a much smaller area. To maximize efficiency, the sunlight needs to be accurately focused. Being off by even a single degree could result in a significant drop in efficiency, and the biggest impact to the cost of delivering solar energy is... Read More »
