Introduction: Home Automation and Security Using 1Sheeld

This is a home automation and security system using 1Sheeld, The project works as the following :

when the user reaches his home door a pir sensor will sense him so a led will be turned on and then he has to say a specific password to can access his home if the password is right the entrance led and the music player will be turned on and if the password is wrong a buzzer will be turned on and the camera will capture a photo of him and tweeted it on twitter and for the kitchen their are a water and a gas sensor if they passed a certain threshold then for sure there is a problem so the 1 sheeld will send you a message on your mobile phone telling you that and if the problem is in the gas ratio the fan will be turned on to push that gas outside your home.

Step 1: Components and Tools Needed

In This project we are going to need :

  1. Smart phone with 1sheeld apllication
  2. 1Sheeld
  3. Arduino Uno/mega
  4. Water sensor
  5. Gas sensor
  6. Leds
  7. Lamp
  8. Fan
  9. Buzzer
  10. Relay module
  11. PIR sensor

Step 2: Code :
