Sun SPOT Allows Wireless Sensor Network Application Development

Sun Microsystems today announced Project Sun Small Programmable Object Technology (Sun SPOT), an innovative, battery operated platform for development of wireless sensor networks, robotics and personal consumer electronics. Project Sun SPOT, which will be demonstrated at Sun's 2006 Worldwide Education & Research Conference this week, opens the door for Java(TM) developers, educators, researchers and hobbyists to build creative applications for the next era of computing -- programming the real world. Powered by a small Java 2 Platform, Micro Edition (Java ME(TM)) virtual machine written almost entirely in Java, Project Sun SPOT provides a way to easily, affordably and quickly build Java-based sensor applications that run directly on the central processing unit (CPU) without any underlying operating system.

The Sun Labs Project Sun SPOT technology evaluation kit will include three Sun SPOTs: two stand-alone devices and one base station. All three Sun SPOTs include a processor board with 32-bit ARM9 CPU, 512 KB RAM and 4MB Flash memory, 2.4 GHz radio and USB interface. Each stand-alone Sun SPOT also includes a 3D accelerometer, temperature and light sensors, 8 tri-color light emitting diodes (LEDs), six analog inputs and 8 general purpose I/O ports for controlling relays, stepper motors and servos. The kit also includes a Java ME virtual machine, NetBeans(TM) 5.0 and a USB cable.
