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!

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

There we got for 10 / 10 for my new project

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!

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

@cranexdragon1046

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.

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!

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?

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

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?

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

Great tutorial thank you so muchh

Good day! I have a problem. :-) I have an error - Simple Timer.h. There is no such file or directory

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

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

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

this is a devic you have to get the app for. the code is here but doesnt work either way.

what about making a connection between ESP8266 with DHT11, MQ2 Smoke Sensor can you make a video explaining it

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 kzread.info/dash/bejne/hIqHpcx8oL3FnrQ.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.
