Touch Based Nurse Caller System

Download Document/Synopsis
We come across hospitals and clinics where disabled people are not able to press buttons in order to call a nurse. Here we propose a touch screen based nurse calling system that allows users to inform nurse through a touch. The system consists of a touch screen used to read user input. The touch input is read and transmitted through an rf transmitter to the remote receiver circuit. The remote circuit receives the input and sends it to microcontroller for processing. The circuit is interfaced with a buzzer and an lcd screen for alerting and message display. The microcontroller processes the signal and sounds a buzzer as well as displays a message on the lcd screen. Touch Based Nurse Caller Project
