Home Automation Project (Part 4)

Hi everyone, this is the Fourth knowledge item for our Arduino Home Automation Project. At the first three knowledge items, I have introduced how to use and setup a WI-FI webserver with using the Arduino WI-FI Shield (Please Click Here for further information about the WI-FI Shield setup.). For the second knowledge item, I have shared some experience on how to use the Arduino MEGA 2560/UNO board to control the servo motor and act as a motor to control the door or the curtain (Please click here for the further information on the servo motor.). For the last knowledge item, I have introduced how to use a motion sensor to be a controller to control the on/off LED lights (Please click here to have further information on the Motion Sensors.).

 

At the same time, I would like to have a short summary on sharing the progress of our Home Automation Project and introduce another function of our Home Automation Project – Feedback System.

Here is a picture for showing the whole circuit of our Home Automation Project:

Most of the circuits of our Home Automation Project are already connected. In the Picture, we can see the Home Automation Circuit will be mainly used with the following Components to perform the Demonstrations:

  • LED Display
  • Servo Motor
  • LEDs
  • CPU Fan

Servo Motor will control the curtain of the house and LEDs will be acted as the lighting system of our house. And now I would like to introduce the feedback system of our Home Automation Project.

 

For the Feedback System, LCD Display will be the most important in the whole circuit. It can display the Temperature and Humidity of our house, the On/Off Status of the LEDs … etc. So, here are some pictures on showing how the Feedback function was working.

In this picture, we can see the feedback system show out the room temperature and humidity by using the Temperature and Humidity Sensor which is connected with the circuit.

In this picture, we can see that if the motion sensor did not detect people movement, it will display “No People” and the LEDs will not turn on.

In this picture, we can see that the LEDs will be turned on when it detected people movement.

So, besides the LCD Display Feedback system, we have created an Android App and this app can control the On/Off status of the LEDs and see the components’ status too! We will share the experience on how to create and Design an Android App with using an online App Inventor.

Hope you will find our projects are useful!
