Touch screen based Wireless nurse attendant calling system for patient or physically impaired

Description

The aim of this kit Wireless attendant calling system is to use design and construct a module that can be used by the patients who are unable to move for calling the nurse and to notify their need which is displayed on the LCD at a remote location with an activating alarm.

The wireless attendant calling system kit consists of the following stages: first the use of a touch screen, reading the touch screen press through the controller and transmitting the signal to the remote location. Secondly to receive the signal, read the signal through the controller and display the data on the 16x2 LCD with an activated alarm.

In this kit wireless attendant calling system, we are controlling the system with the help of a touch screen. As we press the button on the touch screen it generates signals and sends them to the microcontroller and sends it to the input section of the RF transmitter where it is encoded and transmitted with help of an antenna. Now the sent signal will be received by the receiver section and decoded by the microcontroller and the corresponding message is displayed on the LCD. This kit is also introducing the use of embedded technology and its importance in electronics.
