“Today, we are going to discuss about a digital thermometer that displays information concerning temperature and humidity, which are read by a sensor and stamped on a color chart, all in real time. In this Project, I explain the use of the serial OLED display, which is a 2c display that enables the printing of data using an AM2302 DHT22 sensor, with a NodeMCU ESP8266.
In this video, therefore, we have the DHT22, an old and well-known temperature and humidity meter, which sends the collected data to be printed on the display. This will be shown in a colored chart, as in the photo above.”
