HLW8032芯片單相電能計(jì)量模塊單片機(jī)程序-UART接口

ID:600684 · 發(fā)表于 2019-8-16 10:49

L91-01是基于HLW8032的單相交流電能計(jì)量模塊（以下簡稱模塊），該模塊包含一路交流電壓和一路交流電流的采集，通過串口的形式送到單片機(jī)，模塊可以測(cè)量電壓，電流，功率，電量以及功率因數(shù)，例程中僅給出了測(cè)量電壓，電流，功率，通過四位數(shù)碼管顯示。

適用：

Ø 單片機(jī)學(xué)習(xí)、DIY等。

附件包含原理圖，51單片機(jī)的驅(qū)動(dòng)例程，和芯片的Datasheet。
