I want to understant why use an resitor at DHT11 Pin1 and Pin2.... i've never used that (of course, not knowing why) but it's work (and why it's working?!?) Thanks for the tutorial
Hi, for serial communications when there is no signal, we want the pin to be HIGH or 5V and having resistor it will keep it HIGH but if we receive LOW signal that pin can change to LOW. if we don't have resistor it will be be in HIGH state which is needed for communications.
Thanks so much for the video! Got it working first try. I'm trying to get it to display the humidity also on the webpage. I got it to display on the serial monitor but wondering how I could also display humidity on the webpage?
I have explained the code fully and showed how it is done. I am not providing code. I am teaching people so they can do more. so please watch, learn and change the code.
I figured it out. Since robojax is no help i can explain it. place this after the tenperature part of the html page +="Humidity "; page +=""; page += String(hValue, 2); page +=" "; Then at the very bottom of the code where it says "Serial.println(f); tValue =f;" type "hValue =h;" right after it. Then lastly, at the very beginning of the code (line 50 float tValue;) place "float hValue;" on line 51 and it should work.
set it (dht11) as HTTP client. Create database on your web-hosting. Send data using ESP8266 to a php file on your website which records it in the database. Then make another php file that reads it on the website. I will make such videos. But good luck.

I have been getting compile errors for 2 days now. I have tried everything. Removing and re-adding libraries, trying diff code. cannot get this to work.

I cant get this to compile I load the code you used change to my wifi load the DHT library from your site what am i doing wrong I have only one file under libraries and thats the DHT file. I have selected the board correctly. What have I missed ???
Hello, I assume you have watched the introduction video ruclips.net/video/pLvqh57T3s4/видео.html. then please test the sensor without wifi. make sure it prints the temperature on serial monitor. then come to this video to get temperature over WiFi

@@robojax thank you for your reply. I have actually watched the video. Sorry for asking again, but you asked to put a resistor between data and vdd, but even after that the output voltage is 4.83v,which esp32 can't tolerate. I hope you would explain
it seems you did not pay attention. I said in the video. this module work with 3.3V. so don't use 5V at all. just use 3.3V and connect the resistor to 3.3V.
This is not enough. You gotta provide more. You have to watch ESP32 "getting started" video ruclips.net/user/robojaxTVsearch?query=esp32 and also make sure you can use DHT22 ruclips.net/user/robojaxTVsearch?query=DHT22 without any issue.

So are you. thank you.
"error compiling for board Ganeric ESP8266Module" enyone can help me ?
This is not enough. You gotta provide more. You have to watch ESP32 "getting started" video ruclips.net/user/robojaxTVsearch?query=esp32 and also make sure you can use DHT22 ruclips.net/user/robojaxTVsearch?query=DHT22 without any issue.
same here, but resolved after deleting current version of DHT sensor library folder, the folder in Arduino/library of DHT to be deleted, and installed old ver 1.2.3 from www.arduinolibraries.info/libraries/dht-sensor-library
Very helpful. Thanks.

If you want to learn, then you have to listen. If not then get the code and run if you don't need the "blah blah".
