Objectives: Patient Monitoring is an Electronic nurse.

The main objective of this project is to avoid the usage of human monitoring over a wide range of areas where every single parameter must be observed and to be attended in critical cases.

The concept of the project is to monitor every single patient/bed in a ward for the pre-defined parameters such as temperature, heart beat and emergency panic button.

Crystal Oscillator

Crystal oscillators are generally used for microcontrollers.

A crystal oscillator is a device used for generating the frequency required for the operation of the circuit.

WORKING

When the patient press the panic button buzzer sounds and patient bed number on the LCD.

As the temperature sensor is fixed to the patient, so continuous body temperature can be observed .
