The working of this security system is very simple as well.Here a PIR sensor is used for sensing and then arduino used for controlling and then A GSM module which is used for calling purpose. When anybody comes in range of PIR sensor, then sensor sends a logic signal to Arduino board which control and perform the specified task. Here arduino board sends signals to GSM module and gives a call on a set number.  

You can easily install this security system in your homes or offices doors to prevent the entry of un-authorized person. This simple circuit is based on wire loop concept. You can install the wire loop approx. two feet above the ground so that when person enters loop will break and you will come to know. This circuit can be simultaneously fitted in three doors and display the door number on seven segment display whose loop has been broken.  If loop of first door is broken it will display 1 and if loop of first and second door both is broken than it will display the sum that is 3. So you can easily understand where stranger is for example if all the door are open it will display 7 (1+2+4). Circuit is based on CD4511 IC. CD4511 is a CMOS BCD to seven segment latch/decoder.

Face, the foremost distinguishing feature of human body, making you the ‘unique you’, not only gives you an individual identity, but can also save you from security breaches and fraud transactions, can take care of your personal data, and prevent your PC, wireless network from plausible security threats!! Unlike the world of facebook, where you can wear different face every day, here it is the uniqueness of your face that makes all the difference. The fast track technology has brought the world at your finger tips, be it anything, it is not more than a click away. The easier life is getting day by day, the more complex it is becoming to escape from the traps intended to crack and get access to your private data. The growth of e-commerce wholly depends on the integrity of transaction.

BACKGROUND One day at the evening time I was talking with my uncle on telephone. He asked me some question base on my learning means what are you learning? which type of engineering are you doing? He ask me that have you made something new during your engineering? That time I don’t have any answer. But…

In this fast moving world, new technologies have been evolved for every second for our human life style improvement. There have enormous advancement in automobile technologies already and still to come. Because of these technologies, now we are enjoying the necessary comfort and safety.But there are lots of accidents happening now-a-days. It is because of increased vehicle density, violation of rules and carelessness. India ranks fifth in the road accidents over the world.We have the objective to minimize the road accidents due to above mentioned facts in real time using embedded systems platform in low cost. In our project, we proposed few concepts to minimize the accidents due to violating rules and carelessness. This project compromises of alcohol detector, mobile sniffing system, vehicle security system and an emergency system.
