             The need for a device that can detect and extinguish a fire on its own is long past due. Many house fires originate when someone is either sleeping or not home. With the invention of such a device, people and property can be saved at a much higher rate with relatively minimal damage caused by the fire. Our task is  to design and build a prototype system that could autonomously detect and extinguish a fire.             The system uses a fire detector module which gives analog output voltage according to the intensity of fire.The detector is rotated through 180 degree using a servomotor which gives wide angle for detection.When fire is sensed,the Robot is redirected to the position of fire and the pump is turned on.Water is pumped till the sensor detects no fire.

      The project aims to develop a FingerPrint based ATM  Accessing System in which user can make their transactions by fingerprints.  Fingerprint recognition or fingerprint authentication refers to the automated method of verifying a match between two human fingerprints. Fingerprints are one of many forms of biometrics used to identify individuals and verify their identity. A fingerprint sensor is an DSP based electronic device used to capture a digital image of the fingerprint pattern. The captured image is digitally processed to create a biometric template (a collection of extracted features) which is stored and used for matching.       We can use PIC16F877A CMOS FLASH-based 8-bit microcontroller for this project. The microcontroller provides necessary commands for fingerprint searching in the sensor module. In this project, it uses two verification techniques(for more security), the user needs to enter their user name and password, ...
