INTRODUCTIONHome automation technologies in

1970’s has paved way for smart home.

In 1990’s using technologies like ubiquitous computing/pervasive computing smart home projects started.

mainly targeted on helping elderly or handicapped people

OUR SMART HOME SCENARIO

OBJECTIVES: To develop a monitoring and sensing

system.

To gather data and make it accessible.

PROPOSED ARCHITECTURE:

5

Smart home is equipped with both wireless and sensor technology.

Sensors used are divided into two categories:

• Wearable sensors• Sensors implanted in surrounding

objects

6

Wearable Sensors

Pulse oximeter sensors: • monitors the saturation of

haemoglobin with oxygen• ability to quickly detect hypoxemia

Blood pressure sensors:• It help diagnose hypertension and

heart disease

Pressure sensors:

• used for bed monitoring

• tracks the movement and position of residents inside home

Fig iv: Floor Pressure Sensors

10

Infrared Sensors:•track the movement and position of residents inside home

•used as a fall detection device

Fig v: Infrared sensors

11

Vibration sensors:• monitor residents movement

Temperature sensors:• monitor the household temperature

changes

RFID systems:• used to retrieve misplaced objects

12

Water flow monitoring sensors:• monitor water used in a household

The architecture also contains cameras and microphones.

Displays and speakers are installed throughout smart home.

ADVANTAGES

Provide care to patients within their home.

For elderly people it helps to overcome the difficulties in life.

provide a successful aging in home

20

LIMITATIONS

Wearable sensors cause discomfort.

Cost of intelligence

Technology learning curve

Other kind of sensors like motion sensors have limited reliability.

21

CONCLUSION

The proposed design represents a good approach to research in smart home environments for elderly.

Work is also ongoing in making the smart home design context-aware.
