Temperature and Humidity Displayed on 4 Digit 7 segment with Arduino Nano v3

Temperature and Humidity Displayed on 4 Digit 7 segment

In this Arduino Tutorial we will learn how the DHT11 Sensor works and how to use it with the Arduino Nano v3 Board. You can watch the following video or read the written tutorial below.
The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data. The only real downside of this sensor is you can only get new data from it once every 2 seconds, so when using our library, sensor readings can be up to 2 seconds old.
