IEC TS 60747-19-2:2021提供了指示低功率传感器规格的指南，低功率传感器是允许自主供电操作的装置或模块，这有助于智能传感单元的低功率设计。这里，智能传感单元包括智能传感器、终端模块和电源，其可以将智能传感器的输出数据发送到外部。本部分还提供了指示用于驱动智能传感单元中智能传感器的电源规格的指南。基于这些，可以从新设计的低功耗智能传感单元的角度轻松选择和组合智能传感单元的三个组件。

IEC TS 60747-19-2:2021 provides a guideline of indication of specifications of a low-power sensor being a device or a module allowing autonomous power supply operation, which contributes to the low-power design of a smart sensing unit. Here, the smart sensing unit comprises a smart sensor, a terminal module, and a power supply, which can send output data of the smart sensor to the outside. This part also provides a guideline of indication of specifications of the power supply to drive the smart sensor(s) in the smart sensing unit. Based on these, the three components of the smart sensing unit can be easily selected and combined from the point-of-view of newly designed, low-power, smart sensing units.
