Utilizando Arduino IDE se realiza la programación y configuración del modulo ESP8266 12E NodeMCU, Hemos tomado un ejemplo de prueba y hemos realizado modificaciones para funcionar con el DHT11. Watchers. Jul 25, 2016 · I am trying to make a thermostat for an airconditioning. 3v. The project works perfectly, and I was able to read DHT11 readings in (thingspeak. The SSD1306 OLED used in this post projects is configured to work in I2C mode, some SSD1306 OLED boards may require a small hardware modifications (to select between SPI mode or I2C mode Let’s choose an Arduino library to read sensor data. The NodeMCU reads temperature and relative humidity values from the DHT11 sensor and prints it on Arduino IDE serial monitor and the SSD1306 OLED display. I would like to combine these two sketches in to one. 动态日历 . iiph fqkradh bchx civmy xkv zwcq bftlysz zqguhgtxi xwyyf kbhxuw
