You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming: https://www.patreon.com/PaulMcWhorter In this lesson we show you how to measure temperature and pressure using the DHT11 sensor. The needed library does not come with the arduino download, but the video shows you how to intall the needed library. You can get the kit I am using for this series at the following link: https://amzn.to/2I7N4Ek This is a heads up that in lesson 51, you will be able to have a much more practical and elegant solution if you use an arduino nano instead of the uno, which we have been using. Go ahead and get ready for lesson 51 by picking up a nano here: https://amzn.to/2WXTC2M As projects get more complicated in these lessons, you guys really need to get a set of breadboard jumper wires which allow you to make neater connections on the board in your projects. You can pick a pack of these wires up here: https://amzn.to/2XrY5Kq In addition as projects get more complicated, you are going to need a bigger breadboard. This is a reasonable one here: https://amzn.to/2IY4d3M Check out all the great Free educational resources at our WEB site HERE: https://toptechboy.com/arduino-tutorial-50-how-to-connect-and-use-the-dht11-temperature-and-humidity-sensor/ [Disclosure of Material Connection: I am a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to amazon.com.
