Most of the engineering student study digital logic design. All are using digital logic IC’s in the lab as well as outside the lab in their projects and some other application. If you are using IC’s and you are going to solder it on the board, or if you are using an ic but you are not getting the proper output and you are not sure if these ic’s are working properly. It is very inefficient to sit down and check each IC with the help of led and power supply. 

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.
