Guys I have updated the source code. You can get it from my github repo.

These functionalities have been included but they might not be working at some time since it is still under development.

• Update data to Thingspeak every 16 sec interval.
• Receive control modes (Manual/Automatic) from Thingspeak Talkback.
• Intrusion detection

Some things still left to do are

• Integrating GSM module (facing some problems here)
• Developing an Android app to control the system.

Helps and suggestions are appreciated.
