one of the few videos that lead to an application that works immediately.
Good job!
Thanks for your time!
Great tutorial!
Had trouble with my ESP8266 not compiling.
Turned out to be the SimpleTimer Library, here's how I learned to fix it:
// Remove this
//#include
...
// Modify this
//SimpleTimer timer;
// into this
BlynkTimer timer;
Hope this helps anyone with this error.
Thanks again!
You are my hero!
@@LiliZorn Glad it helped you out!
Excellent goodman
Thanks, yes this worked for me as well!
thanks
I copied everything but with a DHT22 sensor. Changed the line to use DHTTYPE DHT22.
In the serial monitor I get "Failed to read from DHT sensor"
Any ideas where I should look for the error?
EDIT: Found the error. The code says DHTPIN 2 but the comment says PIN 4.
And the diagram also indicates to PIN 4. It was actually using PIN2.
The Blynk app is also updating now. Fantastic!
Ty for the edit!
hi man, so did you solve the problem?
I already checked this but it remains the same. Did you do anything else?
Good video! your cellphone is nice! unfortunately the program has been set up at 50 times the speed so the whole thing is useless. Maybe a step-by-step write-up would help ... I'll be successful next time, or else it's not your desk!
Neat !
But how was the humidity 95% ? what was wrong ?
Most likely not. Depending on the location if this was an outdoor garage or workspace that wouldnt be otherwise heated the humidity can easily jump if there is a slight decrease in temp.
your code not working.plz help.
exit status 1
Error compiling for board NodeMCU 1.0 (ESP-12E Module).
Don't forget to install blynk library manually.

There we got for 10 / 10 for my new project
Thanks for the Video. I am having an issue where I used the DHT11 sensor with Arduino Mega and the reading was very accurate compared with another AC controller and sensor that I bought from the store. But when I used the same sensor with ESP8266 the temp reading was accurate but the humidity was off by 5 to 10% which I found very odd. Any idea why is the difference, are you using the same dht11 library with Arduino and ESP8266. Also is there a way to read the fraction temp and humidity or it has to be full integer?
Good evening, I have rebuilt the sensor and works very well with the DHT11. But I want to make a sketch suggestion. A relay should be switched on at a certain temperature and switched off again at a low temperature. That would be great. 2 additional buttons in the Blynk app for on / off would be great. Can you help me with the sketch? Thank you
Hey viral science! I just want to Ask if what ZIP files do you need to make that? do you need to insert zip folders or no?
thanks! now that i got down one sensor per project, how about two sensors or more in one project?
No code no circuit, please send new link
From where can i find the esp8266wifi.h lib ?
hola! una pregunta y si quisiera conectar un sensor de humedad de suelo seria así como tu ejemplo?
Wow! Nice video bro!! Keep going :)
Good day! I have a problem. :-) I have an error - Simple Timer.h. There is no such file or directory
No code, No circuit. Both links are droped. Please, can I reload?
same here.....pls help i need it
Send linksss
same here
Yup. No code & no circuit == supreme waste of time.
Here you have the code

bro what all equipments do u use for making these videos e.g. camera ,mike etc.. and which editor do u use????
The best video about... All internet!
this is a devic you have to get the app for. the code is here but doesnt work either way. BASICALLY THIS IS A QUICK WAY TO PROMOTE THE APP WHICH CHARGES YOU TO ADD YOUR BUTTONS AND FEATURES TO YOUR DOODAD. , ID PAY IT BUT THIS IS A RUN AROUND. [ON TOP COMMENT]- THOSE 7 COMMENTS ARE FAKE COMPLIMENTS.
Greetings, I can not make it work, I've tried everything and it's fine, but the reading does not come in the blynk application, you have to recharge it with money to enable this function? Thank you
I don’t understand, the esp can create a wifi access and i have to connect ? Or esp can just connect to a network ?
I have a problem and I can't not connect my nodemcu to Arduino environment and I have all the plugins! why isn't connect? can you please help me? And thank you very much for your really good good videos I really do appreciate!!
Can you add a fan to act like a cooler on this project??
So, I have a question. Will it hold the results in a spreedsheet of some sort?
what is the name of that simulator app you use to draw ?
In case you didn't find out, the program he used was Fritzing
how you do this but print result with a web server?
Nice video but why a Virtual Pin rather than a regular Analog Pin?
Can I get the connection which you made from nodemcu to sensor it is difficult to see in video
"Failed to read from DHT sensor!
" itried ur code but always failed in node mcu but when i tried to arduino uno it functional pls help
Help, Read failFailed to read from DHT sensor!
hi. i will like to add SuperChart of blynk. Please can you tell me what change in the code??? thanks!
Can we do the same for smoke sensor.
Can someone please help me it says "expected primary-expression before '.' token" on the
"Float t = dht.readTempurature()"
And I don't know what to do to fix it so please help me
Hey, can I use Espruino IDE rather than Arduino IDE?
Also you can use mqtt and adafruit.io
Then you can make control with google assistant
Ifttt
Can you make a longer range RC car with fpv system. I am only asking to you because I love watching it vedios.😍😍😍😍😍
Hey, im not sure how likely you are to respond to this, but what power source do you use to power it without connecting it to the computer? Im a noob so i need to ask
what about making a connection between ESP8266 with DHT11, MQ2 Smoke Sensor can you make a video explaining it
to: Viral Science ; Please tell me may be get data or control Node Mcu ESP8266 from a smartwatch (DZ09 chiness smart watch) (Wifi) ?
Hi, don't you know how can I link this kind of project with my system so that I can also monitor the temperature through the system I've developed. Not using blynk or any other app?
Bro error Saying Leaving
Hard resetting via RTS PIN
Im receiving this error and I dont know how to fix it:
In file included from C:\Users\*****\OneDrive\Documents\Arduino\DHT11nodemcu\DHT11nodemcu.ino:34:0:

Can someone tell me.. is this project in IoT project category????
Great tutorial thank you so muchh
I do not know if all but it happens to me that it does not show the data of temperature and humidity in the application blink being all done well, if it is your case write me and I post a posile solution, greetings.
What is the range to which data can be sent. Like 5 km etc
All over the world just need internet connectivity
Help, I have this error:
'DHT dht' previously declared here
In this line:
DHT dht(DHTPIN, DHTTYPE);
Help Please
Let me ask, how about adding an LCD display?
ruclips.net/video/G0an4VZYi18/видео.html there is a video who is a diagram with no-I2C display. with I2C display it's more easy :) you can find all informations about that on internet :)
bro how to fix hard resetting rts pin problem
Se puede hacer esto con elsensor de Temp. Corporal el Mlx90614
blynk app not working .please send me blynk old version
can i use the coding but using esp32?
Hi, i want to ask all of you guys.. is this project counted as IoT project?? I need to know it because i need to create Iot Project for my course
Hi, there, that is lovely video. It is really clearly explained. Thumps up! ;) May I have a question.. What is the name of the editor that you use for simulation of the el. circuit. Looks intuitive and easy to use. Thanks a lot.
It's called fritzing
Hi anyone has idea why my reading on blynk appears 255 for both temp and humidity? something needs to do with timer?
what is the available distance
not working:
exit status 1
Error compiling for board NodeMCU 1.0 (ESP-12E Module)
check if you have multiple libraries of the same DHT sensor
can we connect sound sensor ,dht sensor ,flame sensor ,ultrasonic sensor to one nodemcu and send notification to blynk?
For that u need to use esp 32... not esp 8266... any doubt u can mail me. anas_ss@ieee.org
Do you have tutorial for acs712 sensor blynk display?
What is that website you are using for circuit making???
Please name of program where you draw this project
i think.. aapne pin 4 me connect kiya hai.. aur declaration pin 5, 6 me kiya hai .. sahi hai kya?
how to download library file for simple timer?
plz let me know im facing same issue
How to make this using mlx90614
Plz make a video on uploding problems of ESP 01 WiFi module
You Got New Subscriber 😊
how we can add ds3231 instead of dht11
can the barometer be added?
do you have the code?
Program got uploaded but wifi not getting connected ..what is the problem
very nice bro. how much an arduino uno and nano costs bro?
Is that the Emperor of Mankind's voice? Omnissiah be praised.

'DHT11' was not declared in this scope
Go under Library Manager, type DHT and enter
You should see a library called "DHT sensor library". Install that and you should be good to go. Not resolved, let me know bro
me sale error me pide libreria simple timer
BlynkSimpleEsp8266.h: No such file or directory
how to download esp libraries and dht
Through library manager bro. for DHT just type DHT and youll see see a library called "DHT sensor library". Install that and you should be good to go.
For ESP library
ruclips.net/video/RVSCjCpZ_nQ/видео.html
This was slow to install so i use VPN to USA and it installed much faster. The DHT library no need VPN as it will install very fast.
how does the esp8266 communicate with the app? through the wifi or internet? i mean...do they have to be in the same wifi network to receive the temperature?
Its is communicating through Internet
You can control it from anywhere
No need to be on same wifi network
Viral Science - The home of Creativity for free?
i don't see the link ....
Can u tell me the simulation u used
Nice project, but i can't stop thingking to pay $166/ each month, is it worth?
the coding is not compiling and a error is coming that an error compiling in nodemce 1.0
cant with lcd i2c?
This code can use with esp32 ???
showing error blynk timer
where can i download the libraries?
Blynk would be great- but for much lower price! Thats why not so widely used yet!
It's the best Arduino video tutorial
Have you removed the code? I can not download it.
There is no option of board of node MCU in tools->board
Please help me fix it
Install esp8266 core i believe thats the library
It does not end it is going and going plzz help
Also node mcu is not turning on after this
links are not opening.
no code links are droped
The code and the circuit are here
URL: www.viralsciencecreativity.com/tutorials/blynk-esp8266-dht11-temperature-sensor
can we use 2-3 separate sensor on single esp8266?
Nope.. only one analog sensor in esp 8266
CODE not found....404 error
can we do the same with sound sensor?
Yes
Идея интересная, только ошибок накуевертил))
Esse app gera o código ou você fez?
How far can the cell phone or blnynk app can see the temperature?
anywhere on the world
What is the app name
