Detailed Description

Power, Voltage and Current sensor BL0397.

The power_bl0397 mupplet measures current voltage (V), current (A) and power consumption (W) using a chinese BL0397 sensor as used in Gosund SP-1 switches.

Constructor & Destructor Documentation

PowerBl0937()

ustd::PowerBl0937::PowerBl0937 ( String  name, uint8_t  pin_CF, uint8_t  pin_CF1, uint8_t  pin_SELi, int8_t  interruptIndex_CF, uint8_t  interruptIndex_CF1  )

inline

Creates a new instance of BL0937 based power meter

Parameters

name	Friendly name of the meter.
pin_CF	BL0937 pin CF. BL0937 outputs a 50% duty PWM signal with frequency proportional to power usage
pin_CF1	BL0937 pin CF1. BL0937 outputs a 50% duty PWM signal with frequency eithe proportical to voltage (SELi high) or current (SELi low).
pin_SELi	BL0937 pin SELi. If set to high, BL0937 outputs voltage proportional frequncy on CF1, low: current-proportional.
interruptIndex_CF	Should be unique interrupt index 0..USTD_MAX_BLP_PIRQS. Used to assign a unique interrupt service routine.
interruptIndex_CF1	IRQ service index for CF1, Should be unique interrupt index 0..USTD_MAX_BLP_PIRQS. Used to assign a unique interrupt service routine.
