Experiments with a Solar-powered Sun SPOT

Sun SPOTs are small, battery-powered, wireless embedded devices that can autonomically sense and respond to their environment. These devices have the potential to revolutionize a broad spectrum of applications - environmental monitoring, asset tracking, proactive health care, intelligent agriculture, military surveillance, etc. Many of these require the device to run for long periods (months) using a combination of duty cycling and renewable energy sources (e.g., solar panels). This note describes lessons learned while collecting data from a solar-powered SPOT for a period of nearly four weeks.
