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!
sir on which software were you doing this circuit diagram? Can you suggest some names where I can do circuit connections and upload codes for demo before on-hand iot for practice.
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.
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!
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!
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
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!!
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?
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
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?
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
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?
th-cam.com/video/G0an4VZYi18/w-d-xo.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 :)
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
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: BlynkSimpleEsp8266.h:18:21: error: version.h: No such file or directory #include
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.
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 th-cam.com/video/RVSCjCpZ_nQ/w-d-xo.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.
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

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.
one of the few videos that lead to an application that works immediately.
Good job!
Thanks for your time!
Great tutorial!

There we got for 10 / 10 for my new project
From where can i find the esp8266wifi.h lib ?
sir on which software were you doing this circuit diagram?
Can you suggest some names where I can do circuit connections and upload codes for demo before on-hand iot for practice.
The best video about... All internet!
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
URL: www.viralsciencecreativity.com/tutorials/blynk-esp8266-dht11-temperature-sensor
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.
Can you add a fan to act like a cooler on this project??
It's the best Arduino video tutorial
Great tutorial thank you so muchh
No code no circuit, please send new link
Can I get the connection which you made from nodemcu to sensor it is difficult to see in video
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?
thanks! now that i got down one sensor per project, how about two sensors or more in one project?
hola! una pregunta y si quisiera conectar un sensor de humedad de suelo seria así como tu ejemplo?

Can we do the same for smoke sensor.
Good day! I have a problem. :-) I have an error - Simple Timer.h. There is no such file or directory
Please name of program where you draw this project
how you do this but print result with a web server?
what about making a connection between ESP8266 with DHT11, MQ2 Smoke Sensor can you make a video explaining it
I don’t understand, the esp can create a wifi access and i have to connect ? Or esp can just connect to a network ?

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
Blynk would be great- but for much lower price! Thats why not so widely used yet!
can any type of NodeMcu ESP8266 used this tutorial??
I am not an expert, but I think as long as you select the correct device you should be fine
can we use 2-3 separate sensor on single esp8266?
Nope.. only one analog sensor in esp 8266
Thanks sir
Nice project, but i can't stop thingking to pay $166/ each month, is it worth?
