Energy Meter HLW8012 Breakout Board
Note: Because of different production batch, This board has green and red two color pcb board. But the function is total same. The color will random send.
Description
Based on HLW8012, single phase energy monitor IC. SOP8 package and simple perpherial circuits.
Need to invasive to AC main power. VBe very careful when use it because of the HIGH AC voltage.
Output power, or current or voltage directly by frequency, which can be read by MCU like arduino.
Current sense by sample resistor
voltage sense by resistors net.
Board dimension is 40 x 23 mm.
Demo code (check in wiki page) support ESP8266 remote debug via telnet, safe to read data when mains AC power connected.\
According to application note, the power supply of hlw8012 must be not isolated, read more information on wiki page.
