This circuit is designed for tracking the location of vehicles. Most oftracking systems are made by using GPS. This is very simple and cheap. Tracking systems are mostly used by fleet operators for tracking a vehicle location, routing and others. This is a very good method for preventing our vehicles from stolen. This tracking system sends us the geographical coordinates and by using these coordinates we can track our vehicle position on electronic maps using internet. By using these tacking systems we can share real time information about transportations. And also can be share real time information or position of trains and buses with passengers. Means passengers can see the real time of arriving busses or trains at the platforms on LCD or on Mobiles.
This project is about monitoring the temperature of some remote area. If there is some area which is difficult to reach and that part is at critical stage. The temperature needs to be below a level but it is not possible to monitor the temperature of that area regularly.Then at this point we can use this model which is so intelligent that it keeps monitoring the temperature of that area and whenever temperature increases beyond a threshold then at that point it sounds the alarm and send the message to the number which is already stored in the microcontroller.
