Explorando o @CheerLights como meio de instrução para a programação da placa ESP32 Heltec V2.

ESP32 + BME280 + VEML6070 + Max44009 + SDS011

This is a C and C++ based IoT project in which we use an ESP32 microcontroller with some modules attached to it. We use a DHT11 module to provide weather data in real time, such as temperature and air humidity, every 10 seconds on an LCD.

Control of the presence of voltage in the network. Control of the presence of voltage of three generator lines, in the absence of mains voltage. Linear current distribution symmetry control.
