Welcome to the forum 
my point still stands… if you found that example, then why are you still asking for DHT11 code?
Are you using an ESP-01? Looks like this…
If so, then you are very limited; Just not by Blynk’s capabilities… but rather by the hardware, in both memory and GPIO… Another thing you will have discovered with some searching about your model type in this forum 
Lots of solutions are available in general… but NO, you will not easily find the exact code for the exact situation… everyone is different and that is why we stress read, read, read… interspersed with try, fail, try again, succeed.
We (other members in this forum) are here to help with specific questions about how a specific commands work, where to find a specific help document, what widget will work best for a specific need, etc… but generic questions get generic answers.
And the answer again, yes… barely… take the DHT example already provided, modify it to work with one of your available GPIO pins and add in whatever other code you need to control the LED with the other GPIO pin.
Note that GPIO pins use different numbering when used in the Arduino IDE. And with that board, you may have to juggle between one of the TX/RX pins to use them for other GPIO purposes.
