Measure 50Hz netfrequency with 1 mili Hz resolution

GO.1: We want to develop a proof-of-concept device that counts the net frequency (50 Hz) with a resolution of the 1 miliHz (0.001 hz). The net frequency must be provided from a 220V to an relevant frequency, and this is the input for the device.

GO.2 We prefer of the solutions is developed on the basis of an ESP32 or ESP8266 prototype board. Using Arduino Mega as the development tool.

GO.3 The solution must report the measured frequency on a USB device port. This port must be configured as a RS232 port/UART in a JSON format, so it’s easy to display the measurement in a PC application or portal.
