These "autonomous sensing devices," which combine sensors as information providers with wireless communication systems, have enormous implications for end users, and therefore tremendous market potential in key sectors such as healthcare, education, food quality control, and environmental monitoring. This National Centre for Sensor Research (NCSR)-Media Lab Europe (MLE)-Higher Education Authority of Ireland (HEA) project focuses on education (sensors integrated with LEGO Mindstorms and Crickets) and the environment (such as wireless networked data loggers for oxygen, carbon dioxide, temperature, and PH).
