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.

Smart home is equipped with both wireless and sensor technology.
Sensors used are divided into two categories:
• Wearable sensors• Sensors implanted in surrounding
objects

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

Infrared Sensors:•track the movement and position of residents inside home
•used as a fall detection device

Vibration sensors:• monitor residents movement
Temperature sensors:• monitor the household temperature
changes
RFID systems:• used to retrieve misplaced objects

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

LIMITATIONS
Wearable sensors cause discomfort.
Cost of intelligence
Technology learning curve
Other kind of sensors like motion sensors have limited reliability.

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.
