How to use DHT11 and DHT22 sensors with Arduino.If you would like to learn more about other temperature sensors, check out the articles below. ![]() Lastly, I will show you how to display the temperature on an I2C LCD. The subsequent examples explain how to read multiple sensors with a single Arduino pin. In the first code example, I will show you how to take temperature readings from a single sensor and display the result in the Serial Monitor. Next, we will look at how to connect the sensor to the Arduino. In the first part of this article, you can find the specifications and information about the different types of DS18B20 sensors. These libraries make communicating with one or multiple sensors super easy. I have included wiring diagrams and several example codes to get you started.įor this tutorial, we will be using the DallasTemperature in combination with the OneWire Arduino library. ![]() ![]() This tutorial includes everything you need to know about using DS18B20 1-Wire digital temperature sensors with Arduino.
