Arduino IoT Cloud and ESP8266 with DHT11 for Temperature and Humidity Monitoring, Arduino Cloud

in my previous two tutorials i explained how to get started with the arduino iot cloud using esp32 wi-fi plus bluetooth module and explained in detail the most basic things which i believe is a beginner you should know in my first video i explained how to control the esp32 on-board led and how to monitor a potentiometer this tutorial will help you how to use digital and analog pins of the esp32 module in my second tutorial i built a home automation project using the same esp32 module i controlled 220 volt ac light bulbs and a fan using my cell phone and computer so if you guys want to control ac or dc loads using relays then you should definitely watch this tutorial in today's episode we are going to use arduino iot cloud with the node mcu hp8206 wifi module we will be using dht 11 temperature and humidity module with the node mcu esp8266 we will measure the temperature and humidity and then we will send these values to the arduino iot cloud where these values will be displayed on the gauges charts and message widgets you can monitor these values using your cell phone or you can also use your computer the dashboard which you can see on the cell phone is automatically generated and i have explained this in my previous tutorials anyways with the help of this project you can monitor the temperature and humidity values from anywhere around the world if you have the internet connection in this tutorial i will also explain how to use the message widget on the arduino iot cloud which you can use in different projects for displaying text messages in this tutorial i will not explain the most basic things which i have already covered in my previous getting started tutorial because the account registration and arduino create agent installation is same for the esp32 and node mcu esp8266 wi-fi mario without any further delay let's get started the components and tools used in this project can be purchased from amazon the company's purchase links are given in the description these are the minimal connections which you can start with if in case you want to use your laptop to power up the note mcu esp8266 wi-fi module you can use these connections for testing your code a 10 kilo ohm resistor is connected between the data and a vcc pen the data pin of the dht 11 sensor is connected with the d4 pin of the node mcu esp8266 wi-fi module now let's take a look at another circuit diagram the dhd11 temperature and a humidity sensor connection with the node mcu esp8266 remain exactly the same this time i added this 5 volt regulated power supply based on the 7805 voltage regulator you will need this 5 volt regulated power supply for the node mcu esp82 esp82665 module because you cannot use your laptop or computer as the permanent power source this is my nodemcu esp8266 development port based on the same connections is explained in the circuit diagram i have already explained the designing and making i will provide a link in the description if you want to make the same development board this is the dht11 sensor to which i have already soldered some jumper wires and i have also soldered a 10 kilo ohm resistor between the data and vcc pins i connected the dht 11 temperature and humidity sensor with the node mcu esp8266 is for the circuit diagram now let's start working on the arduino iot cloud open your arduino iot cloud registered account and follow the same exact steps this header file is automatically added i only edit the dht.h header file you don't need to download this header file as we are using the arduino online editor so most of the libraries are already added this is an amazing thing is most of the beginners find it quite hard to download and install libraries so with the arduino online editor you only need to add this line of code and that's it next i defined a pin to which my thd 11 sensor is connected which is d4 pin and i also define the type of the dht sensor which is dhd11 inside the setup function i activated the serial communication which i used for the debugging purposes to check if my code is working the other lines of code inside the setup function are automatically added inside the loop function the arduino cloud dot update function is automatically added i added this dht sensor git data function which is a user defined function i have placed my dht11 sensor code inside this function i didn't use the functions which were automatically generated but i defined my own function dht underscore sensor underscore get data this is a user defined function it has no return type and does not take any arguments is the input inside this function we are simply reading the humidity and temperature values which are stored in variables humidity and temperature and then we send these values to the arduino iot cloud where these values are displayed on the gauges and charts widgets the message variable is also automatically generated and this variable is used to send a string message to the arduino iot cloud dashboard you can find all the automatically generated variables on the top of the arduino sketch so you have to use these variables to send your census data to the arduino iot cloud so that's all about the programming you can download this code from my website electroniclinic.com i will provide a link in the description i have already uploaded this program let's watch this project in action support me on patreon for more videos i hope you liked today's episode like and share this video with your friends see you in next episode and thanks for watching you
