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 <SimpleTimer.h>
...
// Modify this
//SimpleTimer timer;
// into this
BlynkTimer timer;

Hope this helps anyone with this error.
Thanks again!

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

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?

[HamzaHajeir]

Neat !


But how was the humidity 95% ? what was wrong ?

[asmodeus_gaming]

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.

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!

From where can i find the esp8266wifi.h lib ?

[rustydusty]

your code not working.plz help.


exit status 1
Error compiling for board NodeMCU 1.0 (ESP-12E Module).

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?

There we got for 10 / 10 for my new project

[toddfogleman]

thanks! now that i got down one sensor per project, how about two sensors or more in one project?

No code, No circuit. Both links are droped. Please, can I reload?

[brandlygaming]

Can you add a fan to act like a cooler on this project??

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

No code no circuit, please send new link

bro what all equipments do u use for making these videos e.g. camera, mike etc.. and which editor do u use????

[maherriyadh]

what is the name of that simulator app you use to draw ?

[giovanipellin]

So, I have a question. Will it hold the results in a spreedsheet of some sort?

[heisy]

I don’t understand, the esp can create a wifi access and i have to connect ? Or esp can just connect to a network ?

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!
