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 remote location with an activating alarm. The kit consists of the following stages: first the use of touch screen, reading the touch screen press through controller and transmitting the signal to the remote location. Secondly to receive the signal, reading the signal through the controller and displaying the data on the 16×2 LCD with activated alarm.
In this kit wireless attendant calling system we are controlling the system with the help of touch screen. As we press the button on touch screen it generates signals and sends them to the microcontroller and sends it to input section of RF transmitter where it is encoded and transmitted with help of antenna. Now the sent signal will be received by the receiver section and decoded by the microcontroller and corresponding message is displayed on the LCD. This kit is also introducing the use of embedded technology and its importance in electronics.
