Um mit den ESP-basierten Boards entwickeln zu können, müssen diese hinzugefügt werden (Einstellungen -> Board Manager URLs): "http://arduino.esp8266.com/stable/package_esp8266com_index.json,https://dl.espressif.com/dl/package_esp32_index.json"

Um den DHT11 auslesen, benötigen wir zusätzlich noch eine Library (Tools -> Manage Libraries): DHT sensor libarary for ESPx:
