Before any technology is created, men are using their sense to detect and feel something on their surrounding These techniques have a lot of weaknesses since it will be distract with the surrounding and the range of sense it limited
Therefore human is trying to create something that will usefully help to make them to sense or detect more effectively. System alert is produced using a few electronics components and using d.c power supply in range of 9V- 12 V.
We name it System Alert because it is a universal alert system that we can built anyway we want it. It can be transform to various technique of circuit depends to our needs. We can change it to become alarm to a car, house, or even a lock with a card, and even to use as switch to air conditioner.
The proposed project is to provide a more reliable power supply and more sensitive sensor for the effectiveness sensitivity setting and the direction of the movement. So, it is quite effective system to be used by anyone who wants to know anybody is in their backyard
