DHT11 & NodeMCU Tutorial || Humidity & Temperature Monitoring over Thingspeak
HTML-код
- Опубликовано: 4 янв 2019
- This tutorial is all about Humidity & Temperature Monitoring using DHT11 or DHT22 & NodeMCU on ThingSpeak. It explains how to log Humidity & Temperature data on cloud. We can use Thingspeak as cloud service provider and DHT11/DHT22 to measure temperature and humidity.
This tutorial is for NodeMCU on Arduino IDE. You can also configure ESP8266 board with Arduino to monitor temperature and humidity.

Thank you very much. It works perfectly !
People must dawnload the library DHT by doing: On Arduino menu: Programs -> Include Library -> Manage library -> write DHT and install this library.
There is different types of third programs DHT, which one did you use?
Thx. You've got what I was searching for: the correspondence between real pin and logical pin.
🤩
Thank you so much sir! It has helped me in my final year presentation .
in serial monitor it shows dotted lines "........." like this what i need to do ?to solve this problem
I appreciate thetime you spent on this very much.
Im sure it worked for some but i was getting errors from the start. or is not the same as along with things not being declared. I copied the code and pasted exactly. After trying to fix in ny limited capacity i gave up. Ill try again tomorrow. If anyone knows certain parts to be edited please let me know.
Great video. Thanks.

Rifado mi hermano, nos salvaste el proyecto de IoT
Thank you very much. It works perfectly !
thank you brother is a good station monitoring
Thanks dude it works :3 for dht22 aso
which arduino software are you using ? in my case it is showing DHT.h: No such file or directory
I have a question. Where can I find the library of that ESP module?
thanks my friend. You helped me a lot.
Hello, thanks for this tutorial it was really helpful
thank you very much you are amazing ❤️ . Can you help me sir , I need to power it with a battery so where do put the +ve and -ve battery electrodes ????
My pin was D5 and not just '5'. For anyone that had the same issue not getting the data to work in the serial monitor.
thank you sir for this content, how can you analyse data from imported CSV. because here it's real time data.
Do you need to have it plugged into the computer so that it collects the data or is it not necessary and it can work perfectly?
do we need external resistor (4.7 ohms or 10 ohms) between VCC and data pin in 3 pin DHT11 sensor? Hope you can answer. Thanks
Mast ekdum gg
Great video! Thanks.
Very nice tutorial. Thanks
Thank you so much bro you helped a lot liked subed bruhh❤😉
Bro in serial monitor the o/p is................... Only this happen please guide how I fix it i have changed braud rate 9600
please make same with, pir sensor , flame sensor, hc-sr sensor
excelent video ... thanks...
idk wtf is wrong in my code.... i didnt see any graph or i didnt see any data on my serial monitor.. i tried with 2 or 3 new dht11's .... its not showing me anything
Helpful vedio
I am getting the message in serial monitor as Failed to read from DHT sensor. Can you give a solution for that?
Hey, I had the same problem. Did you somehow solve it?
Same problem!What to do?
check your dht11 data pin true location?
Hello
Thanks for this really good tutorial. But i have a "small" problem : I cannot open a free account on the Thingspeak server site. How can I do ? Do you think it is always possible or not ? Perhaps it depends on country ?
Best regards
Hello dear please make the all video in this youtbe convert to hindi kindly to easy understat everyone thankx
Thank you so much!!!!!!
can you explain, why pin 3 .. I search in your code in arduino ide .. pin dht 11 is D0 .. and i'm connected to node mcu in d0, the function can't work.. but if i connected to pin d3 .. it's function properly... CAN YOU EXPLAIN ????
Read the official DHT test code. It states which pins are most likely functioning.
Sir what is the use of storing the temperature, humidity, and soil moisture values?? Only for the graph or else any advantages using this thingspeak?
I think we can store the data and which is accessible from anywhere in the world like google
And I 'm not sure😊
Can u please tell me about the jumper wires u have used i mean they are male to male or male to female
I am not getting any data on my thinkspeak, ESP32 serial shows data but it seems that is not passing it to the thinkspeak, I checked all coding and no issues; Do I need to set anything else to pass data to the thinkspeak website?
Is possible to use an acelarometer like adlx345, and see the x,y,z graphs?
Hey my friend, how can I make this NodeMCU access the internet through static IP address? What Do I need to change/add on my IDE sketch? Could you help me ? thank you
hi plz if u could help menthe deadline of my project at 24\5
I want to know how could I send information to thingspeak of 3 sensors using Ethernet shield , I know how to send one read of one sensor but when I put the second one it docent work
how to get the esp8266.h library
I had to disconnect the data line from the dht11 to nodemcu board to upload sketch...
read and write API key must put in arduino or just write API key?
Where should i download the lib ?
Hi for me it failed to read from DHT sensor
same here how did you solve it?
Hi
I need one help
When I am executing the program WiFi is not connecting and I am not getting output.
What should I do?
nice video
how to write the ardino ide program?
thank you bro
i got it
can you help me
am try it with your method but I didn't get an output...data not available in thingspeak
Why my output is "......" ? pure dot no data receive? why and how sir to fix this?
same...plz help...i got the same ......output
Same help!!!!
Bro hau to you make node mcu circuit diagram
actually i want to rotate servo motor by giving commands from thingspeak.The command is appearing on the serial monitor but servo motor is not rotating can any one help out???
thanks brother
how can i do this to two sensors(dht11) at the same time?, i would like to measurement two different places.
We need 1 common gateway and two sensor nodes. I will be making videos soon regarding this.
@@HowtoElectronics
is the video available that explain two gas sensors monitoring at same time through nodemcu
@@fathimashifanans2225 you can do the 2 gas sensors project by doing this:
first download and add the libraries to arduino. github.com/E-for-Engineer/DHT11-data-upload-to-ThingSpeak-Using-NodeMcu/find/master
you should have this 2 libs in the link.
write #include to the top of the code.
delete dht. sensor codes and replace gas sensor codes instead of them.
how to connect board to ardiuno ide
Hi
Temperature and humidity not shown in thingspeak
Tel me what is problem
Sir how if I want to include multiple dht11 into the circuit. I actually did my coding but in the postStribg it stated that expected primary expression before '+=' token. How do I solve this problem?
My serial monitor is showing some symbols, not the values.
I tried the same code and same pin. But it printed values only in the serial monitor. No updates in ThingSpeek. I have done the same as you except used my Write API Key, Hotspot, and password. Can you please help?
Hi I have the same problem, if you know the solution, can you tell please 😊
arduino say's to me i have not enought storage
what i have to do?
can you help me? i receive this message "error: espcomm_upload_mem failed"
#help
How can i connect my nodemcu to office wifi? My office wifi need to login first via browser.
It display that is send to thingspeak but nothing is happen in thing speak web
bang, aku udah coba program punya abang. tapi tulisan di serial monitornya Failed to read from DHT sensor. itu kenapa ya masalahnya ? sebetulnya program abang juga ada yang kurang di include DHT nya, tapi itu sudah selesai. masalah aku ada di pembacaan sensornya. itu kayak mana ya bang ?
There are tutorial for sht 3x ?
hi bro
when we did this project exit status error occured
Will this work for esp32???
esp32 how to do
if we use arduino then is the code is same ?
Can you export the data to an excel file.
i have a probeme "
Compilation error for the NodeMCU 1.0 card (ESP-12E module)"
I had the same. If you see the detailed message, IDE misses "Adafruit_Sensor" library as well. just download as well.
Hi ! Is it works with esp32 ?
how do we add the data to a chatbot.
I am keeping on getting this error .. any help?
Error compiling for board NodeMCU 1.0 (ESP-12E Module).
instal library ada fruit sensor master
Have to tweak a bit in board manager settings.
doesnt work for me. followed directions exactly.
its all working fine except my results are always 0c and 0% :(
itu belom working tlol
Very bad ya. If copy & paste the code copy every think unwanted pages will paste not able to remove unwanted
how if i use esp32?
error
no such directory file #include // Including library for dht
You have to add DHT library. refer the previous comment for the same.
cannot find the library file link.....plz specify the library fie link
include the link arduino.esp8266.com/stable/package_esp8266com_index.json in "Additional Boards Manager" under Preferences . Follow the link for detailed instructions create.arduino.cc/projecthub/electropeak/getting-started-w-nodemcu-esp8266-on-arduino-ide-28184f
Sir please why not the analog pin?
Hi, the pcb on which the sensor is attached, already converts analog data to digital.
Sir , why u choosed think speak application sir!!!
Because it is easy and free.
You can choose ubidots also
@@HowtoElectronics then what about blynk app sir
sir i installed library but still error
sir which library include for dht11?
Link is given in description. You can check
@@HowtoElectronics where is the link I'm able to find it and I'm not able to include esp8266WiFi.h
Why is it always dark in india?
didnt work :(, my serial monitor is empty
double-check the baud rate, which should be set to 115200 as per the code. Else change the rate in code as per your requirement.
Failed to read from DHT sensor!
Same
same, any leads on fixing it?
i'm currently trying to figure it out right now
so in my case i made sure everything was hooked up right on the diagram then unplugged the sensor and plugged it back in and then re-uploaded the code and that worked for me
@@plague0810 ur dht11 is now working with nodemcu?
Informative. But how legit is this.
it was showing like this
expected primary-expression before '.' token.
@ float h=dht.readHumidity();
can you explain
sir i want to do the same practical on proetous . can u provided your email id.
