IoT connects devices to Internet and use cloud-based application to connect our daily lives.
This IoT model detects the temperature and humidity readings
Smart Homes:
Detect the temperature and humidity over your
mobile phone and control the home Air conditioner or Heater when you’re still
in the office
Weather Station:
Measure
temperature and humidity, while updating the data on a remote server that can
be viewed by the public
Materials
& Components
Arduino UNO (Arduino is an open-source microcontroller based on easy-to-use hardware & software)
Esp8266 Wi-Fi module (The ESP8266 is a low-cost Wi-Fi chip that allows the Arduino to send information through the internet. Also, it needs an exact voltage of 3.3V ) Refer: Wiki
DHT11 Temperature & Humidity Sensor (The DHT11 is a basic, ultra-low-cost digital temperature and humidity sensor for Arduino. It needs a 3.3V-5V voltage input. Refer: Github
Resistors (four 10KΩ resistors)
Note: If you come across any issue with ESP module, use three 1K resisters for voltage divider & connect 10K resister in-between pin 4 & 8 of the ESP module

Build your model
Connect DHT11
& ESP module to Arduino as per the diagram
Connect the
circuit by using jumper wires & bread board
Create a
ThingSpeak account (ThingSpeak is an open source IoT application made by GitHub that retrieves & store data from IoT devices (things) and displays it on a friendly graph that can be viewed by the public. You can create a free ThingSpeak account by logging to ThingSpeak
Connect the
Arduino to computer through serial cable & do the coding
