Introduction:

Are you worried of the valuables that you have at your home when you're out on a trip or at your office? If yes, then this project is just for you! A security system which on detecting the presence of a human at your house will text you wherever you are that there's a problem. That sounds good, isn't it? Well, this is what this project does.
The project uses the 'multi-talented' Linkit ONE as it's brain. When a PIR motion sensor connected to this board detects some kind of motion, through it's GSM feature, the board sends you a text message. The best thing about this project is that it can be completed within 1-2 hours and no soldering or drilling is required to make it. This makes this project a great way to get started with Mediatek LinkIt One.

Parts and Tools required:
The following parts and tools are required to make this project. The total cost was around $70 or 4200 INR. The best part is that no soldering skills are required to make this project. All the parts can be found over online stores one of them being seeedstudio.
Parts:
  • 1x LinkIt ONE board
  • 1x Lithium battery to power your board (included in the Linkit one kit)
  • 1x GSM antenna (included as well)
  • 1x PIR motion sensor
  • 1x Sim card (shouldn't be pin locked)
  • 1x 5v adapter (optional)
  • Male to female jumper wires
  • A suitable enclosure for your project
Tools:
  • Hot glue gun w/glue sticks
  • Drill (not mandatory)

How it Works?

The process is quite simple. When a human approaches in front of the sensor or the security box, the motion sensor gives a high output which is detected by Linkit one. Through it's GSM feature, it will text you that a human was detected at your house at that time so you can take a suitable action at that very moment. The best part is that you will get a message through this box no matter in which corner of the world you are! The only condition is that there should be a mobile network available at that place. Now don't expect that this would also work on mars :P
The sensor that is used to detect motion of a human being is called PIR motion sensor which stands for Passive infra-red. It works with the fact that every human (actually everything) in this world emits a certain amount of infra-red radiations which is detected by this sensor. It gives a high output which remains high for some time under such condition. The range of this sensor is around 6m which is pretty sensitive and can be varies though a preset present on it.
