Abstract :
Abstract In order to speed up the doctor's or nurse's time reaction in providing patients with rapid care, the nurse caller gadget is utilized as a specific communication tool between the patients and the healthcare provider inside the hospital. The two parties' communication is more efficient and organized when the wireless nurse caller device is used. The microcontroller ATMega8 is linked to the Bluetooth module MH-10, acting as both the transmitter and the recipient. A microcontroller known as ATMega8 processes the data, generating characters on the LCD, turning it on, and sounding the buzzer to summon the nurse or doctor.
