Energy Meter HLW8012 Breakout Board

HLW8012 Breakout Board

Based on HLW8012 Breakout Board, single phase energy monitor IC. SOP8 package and simple perpherial circuits. HLW8012 is the backbone of the pressure measurement. And the circuit has an internal ADC circuit.
Need to invasive to AC main power. VBe very careful when use it because of the HIGH AC voltage.
Rate current is 20 ampere
The module uses voltage divider to measure voltage. High accuracy. And use a resistor for measuring current.
Use pulse width communication. Compatible with all microcontrollers.
Output power, or current or voltage directly by frequency, which can be read by MCU like arduino.
Voltage sense by resistors net.
Current sense by sample resistor
