IoT : Internet of Things

on


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 

 Please Note your ESP & DHT pin lay out/connectivity may change
