HT5019 datasheet: https://datasheet.lcsc.com/szlcsc/180...

In this video, I reviewed a multifunctional device for monitoring a 220 volt household network. This device combines the functions of a voltmeter, ammeter, wattmeter (power meter), electric energy meter and frequency meter. The video showed in detail how to use this device.
The wattmeter has only one button. A simple press turns the backlight on and off. If you hold it for 3 seconds, then the input of the power value will appear, above which an overload warning will appear. If you hold down the button for 5 seconds, the value of the consumed energy will be reset.
This device can measure voltage, active power, do not confuse with full power, amperage, power factor, consumed energy, the values ​​of which are retained even after power loss, and mains frequency. The kit includes the wattmeter itself, an external current sensor and instructions for use.
