HT5019 datasheet: 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.
