Remote Power/SWR Meter

This WT32/ESP32 based project, combined with a directional coupler setup, allows you to remotely monitor the output power and SWR of your station via a web browser.

To achieve this, it reads two voltages which are supplied by the drectional couplers. From these, the respective power is calculated with the help of a table to be created by the user.
