I have tried several tutorials of how to get ESP8266 and DHT22 work together. No one has worked. But so did yours! Thank you!

[ashutoshchoudhary]

What an excellent, simple and amazing explanation. Loved it really.

[canggihtechstore]

Thanks Robojax. Your code works on first try! I will expand it further to upload to google sheet later.

[andrewmagdaleno]

I'm saving this for later. I love your videos, so organized and concise! Thanks!

[alinemariamilagres]

thank you from Brazil. Best one i've seen so far.

I have been trying to connect a ESPEP01 to a DHT22 for weeks, I know the sensor works I am connected to GPI02 but I receive no data. Any help gratefully received

[tsetsefly]

Hi @Robojax, is there a way to send multiple sensor data types, or do you repeat code using a different value with the float command?

[Codality]

A very well explained !
Thx a lot for your time and effort
I am getting nan, I don't know why
I tried to fix a lot but still not working

[upendrah]

Like no 786. Thank you for sharing valuable information.

[geektechsupportservices]

have to say, for a newbie, it took me some time to get this working but once i did i loved it. Just one question how do you get both settings to display in separate lines?

[benjibeatsboy]

Connecting DHT11 directly on your ESP8266 is dangerous no?? My teacher told me to connect the ESP to my arduino uno first

[youssefdirani]

I had DHT11. The "DHT Library on GetHub" you linked to in your webpage, when I installed it, it failed to compile, asking that there is an include to adafruit that is not recognizable, something like that. But when I used the "DHT Library from Robojax.com" it compiled, AND WORKED LIKE A CHARM !!

[cerberusdarck]

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

[vincentngiyimouh]

This is so helpful and easy to apprehend thanks Robojax. Will so much appreciate if you can assist me on how to safe this data with date and time. The information here refreshes after 3 seconds no way to do data monitoring.

[nourboukaily]

Thank You!! working perfectly...but one question please i want to display data on webserver on a table already done with that but moreover i want new data to be printed not editing the current one on webserver.(each periode of time create new row on table and print value and keep the old one).. can you help me (sending any useful website...) thank you in advance !

[midsfb]

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?

[AZal]

I am using an ESP8266-01, an arduino and a DHT22, but currently the sensor is giving me a temperature and humidity read of 2147483647, what can be causing this? I tested the dht to see if it works and it should work properly

[prakashkar]

I have DHT11 module with registor. It Works well with Arduino UNO but not with NodeMCU. I thought it might be issue of in-sufficient power. So powered DHT separately from Arduino 5V out (Ensured same ground for UNO and NodeMCU) but still not working. Kindly suggest the solution.

[daveveautour]

After running the arduino sketch is the code then permanent on the esp8266, or do you need to always to have it connected to arduino?

[auclpg]

Thx from germany.
That was helpful for me.
i like how Slow your speak and Show it

Is ist possible to use more than one DHT11?
Maybe you can help me?
