This mixed mode interface combines the traditional analogsensor signal with a low cost serial digital link to access a transducer electronic data sheet (TEDS) embedded in the sensor.
Back-end processors are used to analyze sensor signals, once they have been converted from analog to digital formats, that have been collected by the RF devices.
一旦射频设备收集的信号从模拟到数字的格式转换之后，后端处理器将对传感器信号进行分析。

You then have analog pins 3 to 6 available for sensor input; assuming pins 1 and 2 are reserved for use by the Ethernet shield (see Resources for more about pin usage).
