Online solar charger and temperature monitoring based on the ESP32. PWM solar charger charge 12v lead acid battery. YX850 switches two big 5v powerbanks (60Ah) and is measured with INA3221.
Project is devepoled using new version of Blynk 2.0
To build a project, you need to download all the necessary libraries and create the settings.cpp file in the src folder:
// Project settings
#include "IPAddress.h"
struct Settings
{
const char *wifiSSID = "YYY";
const char *wifiPassword = "ZZZ";
const char *blynkAuth = "XXX";
const char *version = "3.0.0"
};
