Wireless Sensor with Low-Power Radio Link:
Device samples data periodically or triggered by event; low-power electronics "wakes" periodically to transmit data or to listen for incoming message to transmit data. Uses simple RF transmitter or transceiver to send data -- either proprietary or standard wireless protocol such as ZigBee. Firmware designed to minimize power to maximize battery longevity.
