This example consists of three programs a sender, a receiver, and a router which are intended to run on different motes. The sender program requests sensor readings and broadcasts the results on the radio. It also uses the LEDs to indicate increases in temperature (red), humidity (green) and light (blue). The Receiver program receives sensor readings from the radio and also prints out data vaoues and uses the LEDs. The router program perfoms simple upstream routing for sensor reading data types.
The receiver consists of components to receive data via te radio and to display the results on standard output.
