i am fresh new and i have DHT11, CH340 USB to ESP8266 ESP-01 ESP-01S Programmer and Arduino IDE...
I found code for DHT11 to show me Temperature and Humidity through WIFI in Web browser, but i cannot find anywhere code which can send data to Adafruit and be visible there.
Also this code should be transferred from Arduino IDE to ESP-01 through CH340 USB programmer without reporting errors.
Does any know what should i add to existing code that works, to be able to read sensor data on Adafruit page or does any knows where to find complete code for this?
I've deleted/merged your other cross-post @neznamnista.
Cross-posting is against the rules of the forum. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend 15 minutes (or more) writing a detailed answer on this topic, without knowing that someone else already did the same in the other topic.
Repeated cross-posting will result in a suspension from the forum.
In the future, please take some time to pick the forum board that best suits the topic of your question and then only post once to that forum board. This is basic forum etiquette, as explained in the sticky "How to use this forum - please read." post you will find at the top of every forum board. It contains a lot of other useful information. Please read it.
Did you look at the Adafruit IO documentation? Right there in the "Adafruit IO Basics" they have a tutorial "Adafruit IO Basics: Temperature & Humidity":
Yes, it's for the DHT22, but adapting the code to DHT11 is a matter of a tiny change to a single line of the code.
Adafruit IO is in the cloud. That means you need to send it data over the Internet. The only way you could send the data through the CH340 is if you had some application running on your computer that receives the serial data from the ESP8266 and then sends it to Adafruit IO via the API: https://io.adafruit.com/api/docs/#adafruit-io-http-api
But why do that when your ESP8266 can send the data over the Internet without any need for the computer?
well thanks for your reply
i have no experience in this
i wanted to create gauges for humidity and temperature and also for esp8266 relay to be everything on one place
main reason is to have dashboard on the phone (android) to have everything (esp8266 relay, dht11 and sonoff basics) on one place and to be free of course
The code is one of the examples of the Adafruit IO Arduino library. You can get it, and the required dependencies by doing this:
(In the Arduino IDE) Sketch > Include Library > Manage Libraries
Wait for the download to finish.
In the “Filter your search…” box, type “Adafruit IO Arduino”.
Click on “Adafruit IO Arduino by Adafruit”.
Click the “Install” button.
Wait for the installation to finish.
In the “Filter your search…” box, type “DHT sensor library”.
Click on “DHT sensor library by Adafruit”.
Click the “Install” button.
If you’re using Arduino IDE 1.8.10 you should now see a dialog asking you whether you want to install the dependencies. Click the “Install all” button.
Wait for the installation to finish.
In the “Filter your search…” box, type “Adafruit MQTT library”.
Click on “Adafruit MQTT Library by Adafruit”.
Click the “Install” button.
Wait for the installation to finish.
In the “Filter your search…” box, type “ArduinoHttpClient”.
Click on “ArduinoHttpClient by Arduino”.
Click the “Install” button.
Wait for the installation to finish.
Click the “Close” button.

Make sure to set your Adafruit IO user name and key and your WiFi router’s SSID and password in the “config.h” tab.
It says much more than that. “exit status 1” is just the generic error message that only tells us something went wrong. There are a near infinite number of possible causes of this error. You need to scroll the black console window at the bottom of the Arduino IDE window up to see the specific error messages that will tell you what went wrong.
Please do this:
When you encounter an error, you’ll see a button on the right side of the orange bar “Copy error messages” in the Arduino IDE (or the icon that looks like two pieces of paper at the top right corner of the black console window in the Arduino Web Editor). Click that button…

You're welcome. I'm glad to hear it's working now!
A common cause of temperature sensors reading higher than room temperature is local heating from electrical components near to the sensor. The solution is to mount the sensor away from any sources of heat. The biggest source of heat usually is the voltage regulator, but the microcontroller and other components will also generate heat.
