The people who are Deaf and blind people face everyday challenges in identifying the occurrence of household sounds like door bell. Designing and implementing a low cost stand-alone device for deaf people for notifying the doorbell ringing who live alone in their house. Face image will be capture face will be recognize if the person is known is or unknown, and alert using vibration pattern. Health monitoring system is provided which will track the heartbeats, temperature and location of a person. Proposes a low cost, reliable and efficient system to alert the deaf or hearing im-paired person consisting of two modules- a transmitter installed at the door and another is the receiver, a wearable device.
