Thank you for this video. I just bought that exact board you show, but in the other tutorials I've seen it mentions that 10K resistor. I didn't realize it was on the board and ready to go! I don't have to search through my box of parts for a through-hole part I'm not sure I even have anymore.

Hi and thanks a million for this tutorial - works perfectly! I followed the instructions on an RPI3B, runs just fine. Keep on the great work!!!!!

[@justfreddy8010]

I followed your tutorial and it worked great.... Thank you for doing this....... Just need to figure out how to get remote access to the temps. Great job....!!!!

Great video -- the other videos I found all were running theirs through a breadboard. Which might make sense to people familiar with electronics but in a practical sense, why would you have a temperature sensor hooked up through a breadboard? These are supposed to be discreet setups for monitoring temperature/humidity. Mine is going to our barn so we can monitor the temperature for our animals. It's a headless setup, I just login via ssh from the house and I can check on how warm it is out there. -- Keep it up, straight forward tutorial, not overkill and applicable to the real life user.

great job!!, did you try to send data to azure iot hub? i am looking for that step as well, thanks!

[@markdurrow]

Have you tried the adafruit cricket hat for robotics? Love these videos. Thank you.

[@PhG1961]

Nice. Try making a video with the D18S20!

[@billloveless6869]

Your code didn't work on my sensor. Why? I made the mistake of ASSUMING that it was a DHT22. It was not, it was a DHT11!! NOW EVERYTHING IS WORKING GREAT! THANKS FOR THE INFO! Check your sensor to ensure that your using the code for that sensor.

[@aawu9690]

sorry, why am i always getting 0 and 0 from the sensor?? thank you!

[@tranquil123r]

much thanks for this video. its good and understandable without breadboard. If you can, can you please explain if the direct connection to the Pi has any adverse effects? like burnout or something? (I had a fan removed to accommodate the sensor.).

[@chadmckean9026]

this is a pull up resistor, it is there to make data readable without trying to deal with quantum physics, the resistor can be anywhere from 4.7K to 10K Ohms, we do not use the internal pull up resistor in the pi as the value is outside of that
the pre-made board also has a capacitor (100uf) to stabilize voltage at the sensor, depending on wire gauge/length and other loads on your 3.3v this may be unnecessary in a DIY solution

[@thewalkingdead1215]

How do you bring this data into python? For statistical analysis

hey, thanks for the video, i have pi zero wifi and following your video i get only DHT sensor not found, check wiring no matter what i try .. any help ? thanks

[@LouisAmiot]

Same as you, did you find any fix for this? :)

[@GuyA]

@@LouisAmiot no sir, just moved to arduino

[@TheNoroLP]

Works great, thank you!

[@jayeshalagh1101]

Too good content.
Please make a video of NRF24l01 with raspberry Pi
Please 🔥🔥🔥

How do you save?

[@ramit_arko]

(ctrl + x) then press Y then hit enter. that's saves auto before it exit the window. for manual save just press (ctrl + O).

[@markstart00]

perfecto

[@WhitbyStuff]

I'm pretty sure that every example about this on TH-cam is now out-of-date and no longer works.
