Arduino Uno R4 WiFi LESSON 31: Measuring Temperature and Humidity Using the DHT11

Pick your Sunfounder kit up so you get the same results I do:

You can pick up the neat jumper wires I showed in the video here:

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:

In this video I show you how to use the DHT11 sensor to measure temperature and humidity on the arduino. I show how to connect the sensor up and how to program it. Enjoy!

Paul, please could you include in this series of tutorials SPI & I2C communications using the R4?
I find your way of teaching excellent and would like to take this opportunity to thank you for all that you've taught me. Thank you very much.

With lots of trial and error, I finally got my homework working for this lesson I learned a lot from it. Great lesson. Thank you.

For some reason my DHT device did not work, so I went back to the device used in the R3 course and it worked fine. Homework tomorrow. Homework up now.

Despite I love this course and channel, I gotta point out this: Enterprise products do not use delay function. They use switch case.
Also, enterprise coding style uses software layers: app, middleware, driver, erc., instead of a single c/Arduino file.
But I ❤ Paul

My homework is now on my homepage. I like the video. Thanks

Hello, I have got my Arduino Uno R4 WiFi later, because it was sold out. Because you are very excellent successful, they could not produce enough! So I am working with former lessons, I love this very much ! I can use it also for Model Railroading. Thank you so much, please I want ask something other: What is this with "artificial intelligence" ? Best wishes, Hans from Germany!

thank you so much for this video series!!!

Dear Paul, the DHT11 data sheet is requesting an 10k pull-up resistor between data pin and the 5V pin. I have checked with and without the resistor and alway the same result. What is your opinion?. Thanks for the great lessons.

Your website looks very professional. Did you create it or outsource?

I have uploaded my homework solution to my YT page, but I'm NOT able to post the link, without getting it removed :-(

[sahilsaini]

Sir I think you should create a WhatsApp community or social community on any platform where we can ask you our doubts

Homework done, but having trouble sticking this comment.

Thanks for the great lesson, Paul! Please see my page for my homework solution titled "Homework31: Working with the DHT11 temperature / humidity sensor".
