摘要
A wireless sensor-network system has been developed that achieves a compact and flexible sensing node. Allocating most of the sensing-control block to a remote host enables miniaturization of a node, which contains necessary minimum function blocks. The sensor configuration is determined by the host to meet system needs and sent to a node as a command with a radio-frequency transmitter. The bit rate is high enough to send sensing data and receive commands. The prototype of a node occupies 22.5 cm 3 and consumes 150 in Win the active mode and operates with a 2-MHz bit rate using a 315 MHz carrier frequency.
