ESP8266 Weather Station using Blynk 2.0 | All-New Blynk 2.0 | DHT11 Sensor

In this video, I will show you how I made a Humidity & Temperature Monitoring system using a DHT11 sensor and Node MCU board. I also show you how to set up an all-new Blynk 2.0 platform.

You will learn
1. How DHT11 sensor works
2. How to interface it with Node MCU
3. How to set up the Blynk2.0 web dashboard and mobile dashboard.

If you are having problem like this
sketch_nov06a_iot:22:10: fatal error: BlynkEdgent.h: No such file or directory
Multiple libraries were found for "Blynk.h"


Then download the zip file of the code from github(link is in the video description).
Unzip the zip file and open it.
Then edit the .ino file as you like.

This problem is happening due to the header files are present in the folder where the .ino file is saved

Nice overview of how to get started on the new Blynk platform.

[jamestabla]

Hello nice overview. did do it and it works but can you help me I'm doing same project right now and i want to add soil moisture. what part of the code I will remove and add? thank you so much

If you had placed the NodeMCU directly to the bottom of the case, you don’t needed an additional microUSB Port to power the NodeMCU, because the NodeMCU has already an microUSB-Port for power. If you use 2x WS2812b LEDs instead of 6 separate LEDs, you only need 1 instead of 6 GPIOs. But I like your project - it’s nice and very good documented!

Great job. But the last blynk version got eventor but at the new blynk 2.0 dont have. Any idea to create inventor if i want to give notification if the tempreture is high or low. Or to give control a water pump on button if the tempreture is high. Please

[goricroyale]

At 18:12 what did u said press reset button which button Nodemcu's ???

[taranagnew]

are both sets of lights for the same thing (temp and humitidy)?

[goricroyale]

How did you powered Nodemcu Direct through your laptop or do u use any adapter.

[JashanjotKaur]

Thanks for the helpful tutorial. I am stuck with this error. fatal error: BlynkEdgent.h: No such file or directory. Please elaborate in detail on how to solve this issue. I have already read other comments regarding this but am still unable to solve the issue.

[Flowerhgg]

Plz suggest code for geting the alert notification on blynk 2.0

[BiswajyotiDebnath]

This was helpful. And, can you please mention the total cost we need to make this device?

[mr.bianchirider]

I thought in Blynk you want to keep the loop clean ?
