Java Distributed Data Acquisition and Control

JDDAC (Java Distributed Data Acquisition and Control) is a platform for building sensor networks and data acquisition systems. JDDAC enables Java applications to interact with the physical world by providing the means to manage transducers and to access measurement data streams. JDDAC is based on the IEEE 1451 standards for smart transducers, and it is available for the J2ME, J2SE, and J2EE environments.

JDDAC has been used in a variety of applications ranging from simple desktop measurement setups to field deployments of sensor networks. Applications powered by JDDAC have been chosen by James Gosling, father of the Java programming language, to receive Duke's Choice Awards for innovation in Java in both 2005 and 2006. NetBEAMS, an oceanographic sensor network monitoring the water conditions in San Francisco Bay, received the Third Annual Duke's Choice Award in 2005. OurTraffic, a real-time traffic monitoring system, received the Fourth Annual Duke's Choice Award in 2006.

You can learn more about JDDAC through this introduction slide set. You can also explore this project, and subprojects related to JDDAC, through the bold links in the navigation bar on the left. We invite you to download the JDDAC software and try it for yourself. You can also check out our mailing list archive to see what's been going on. And if you have an interest in interfacing your Java application to the physical world, we'd love to have you join us!
