DHT22 with Arduino - Humidity and Temperature Sensor with Touch Screen LCD 

I bought some dht sensors for building an arduino-based automatic ventilation system for the house... the design phase has now lasted for 2-3 years with no end in sight :-)

NOTHING TO SAY GREAT GREAT GRAPHICS.ALMOST DONE FOR MY 2.4 MCU DISPLAY.

Really nice interface you programmed, thank you!

Very good and very helpful project. I like it 👍

Another fantastic project love it!

Very good video, big help for me.

Hello, please tell me how to add support for displaying the clock with the day month and year with DS3231 to your program with temperature measurement, I will be grateful for your help.

can I use 2.4 inch tft screen with the same code??

I wish you explain each line code to create this beautiful app. Especially the one on the right at 9:07. How do you draw the meter with a indicator needle?

Hi...Very nice project !!! Currently, I am using MLX90615 sensor for temperature measurement. but the temperature on the Nextion (7 inches) is not changing. Will you please guide me regarding the same ?

Hi Gadget Reboot, I'm trying to use your examples in this video because I really like how you made the meters for the display however I'm having some difficulties getting it right... You need to remove your link in the description from MCUFriend because that link doesn't work anymore, also because of that I got redirected to the Seedstudio or something like that and I installed their stuff to my IDE to test their example code and libraries and I had to remove it all because nothing works, the code didn't even verify or upload to my Arduino UNO so I've been wasting my time trying different things and got nowhere. I did learn that I need to combine some of your code with my own and some Adafruit Libraries needed to be installed using the Library Manager withing the IDE software to ensure that I have the correct and latest versions plus some extra dependencies had to be installed just to get the sensor working, now I have to do some magic for my display because that wasn't easy to figure out either, after hours and hours searching online nothing really compared to my situation, even the manufacturer doesn't have the correct example code and info to get it working. Finally after installing a lot of missing libraries and dependencies I finally got the graphics demo actually working and I see something else than only the white screen, the SD card and resistive touch haven't come to life yet so I need to do more work on that too. Don't you find it frustrating finding the right info online if you have something new you want to test, especially the displays because not one tutorial that I could find online is for the one I have... If you're interested my display is a 2.8 inch resistive touch shield from Velleman, here's the link to the official website - www.velleman.eu/products/view?id=435582 Velleman is a brand that you'd expect to be of better quality and have better documentation, certainly I had to pay more but it's just as frustrating with their products as with the cheap Chinese stuff, maybe I was lucky but all products that I've purchased from China just worked instantly without any issues, both the Arduino UNO and Nano worked out of the box, I didn't have to fool around with the bootloaders those were pre-installed just as the driver I needed to install for the custom chip just worked and best of all are the unbeatable prices. I'll fork your GitHub repository for the DHT22 sensor and I'll make the necessary changes to get it working with my display I hope, maybe you want to add my changes to your own repository when I'm done or maybe we can do some projects together in the future, if you're interested you can find me on GitHub here - github.com/soharddbwarez

Can you please tell me, How to interface ams AS7341 sensor with Adafruit 2.8" TFT Display Breakout Board through ARDUINO UNO ? Please Please..................!!!!!!!!!!!!!!!!

What will happen, if you try to read before 2 sec.

Hey wanted to let you know that you missed a step that is really important for people using different Touch screens wondering why the touch wont work they have to calibrate it with the run TouchScreen_Calibr_native.ino in MCUFRIEND_kbv examples And enter the XP =# , XM =# , YP =# , YM =# ; //Screen size ID=number TS_LEFT =# , TS_RT =# , TS_TOP =# , TS_BOT = # mine looked like this const int XP = 8, XM = A2, YP = A3, YM = 9; //320x480 ID=0x9486 const int TS_LEFT = 126, TS_RT = 912, TS_TOP = 950, TS_BOT = 97; in the example it was this const int XP = 7, XM = A1, YP = A2, YM = 6; //320x480 ID=0x0099 const int TS_LEFT = 903, TS_RT = 163, TS_TOP = 947, TS_BOT = 165; and i was so lost why the touch wasn't working i see in the code it says to run it but someone who's just going to copy and paste won't understand why. love the content!!!!

hi! amazing video and thanks for your explanations! May you splain me how we can do to use same code with 2,8 inch touch screen? ks0257? i ve tried changing some initialicing numbers but any result... thanks anyway!

This is an 'annoying' sensor with regards to programming. A good alternative is: "Adafruit Si7021 Temperature & Humidity Sensor Breakout Board" --> github.com/vanvught/rpidmx512/blob/master/lib-bob/src/si7021.c
