    摘要： Disclosed is a telemetering system that comprises a wireless base station and a number of wireless sensor nodes. Each wireless sensor node includes a solar cell, a sensor for producing observation data indicating a quantity being measured, a wireless interface for receiving the observation data from the sensor when the node is activated, and a time-schedule memory for storing time-schedule data. Control circuitry briefly activates its own node by supplying power from the solar cell to the wireless interface at periodic intervals according to the time-schedule data of the memory and briefly establishes a wireless link to the base station. During the time the wireless link is briefly established, the control circuitry of each node transmits the observation data to the base station and updates its time-schedule memory if it receives time-schedule data from the base station.
