SCOPE AND LIMITATIONS

The scope of this project is to develop a self-health monitoring device that is easy to be used. This is because the users that will use this device could be an elderly people or people with low knowledge on the medical devices. Therefore, there shouldn't be any bulky wires and a lot of complicated procedures or connections between the devices and the users. However, a certain limitation has been put considering the restricted time and resources that are available. This is to ensure that this project title can be completed during the period of studies and are achievable.

The limitations that this project title has are that the sensor or transducers used are probably old-fashioned and the used of many transducers are acquired. For example, there are multiple researches and development had been done on measuring oxygen saturation in blood (Sp02), blood pressure and heart beat using Photoplethysmography (PPG) method. However considering the time frame given, the research and development of these sensor will caused the project to be unable to complete in time. Therefore, the used of basics sensor in measuring the parameters are chosen. This in return will make the Self-Health Monitoring kit to operate with maximum circuitry.

The other limitations are the budget or cost. Since there is limitations in the budget for developing this project title, the used of sensor node (wireless node) are not advised because one sensor node can cost up to hundreds of dollar. Since this project requires up to four transducers, the cost could be high.  

In order to cover the above major draw backs of the design for this projects, the used of Bluetooth module is incorporated to form a two way feedback's between the users and the doctors. This function is much important so that patient’s condition can be monitored and if there are any abnormalities in the readings, the doctors can alerts the patients and advised them to come to hospital for further treatments.
