The Benefits of Adopting a Wireless Nurse Call System

The nurse caller device is used as a special communication device between the patients and the doctor or nurse 
within the hospital area as a means of speeding the doctor or nurse's time response in providing immediate care to 
the patients. The use of the wireless-based nurse caller device makes communication easier and neater between the 
two parties. The Bluetooth module MH-10 is connected to the microcontroller ATMega8 as the sender and 
receiver. The information is processed using a microcontroller ATMega8 that produces characters on the LCD, 
turns on the LED, and activates the buzzer to call the doctor or nurse.
