| Summary: | Wearable Doorbell Notification for Deaf People is a wearable device to alert the deaf
people who supposed to be the wearer of the device whenever there are people pressed
their doorbell by using the wireless technology, nRF24L01 wireless module and
Arduino Nano to produce the device with additional components such as push button,
LED, LCD and vibrating motor. Most deaf people were using light doorbell notification
that was placed in certain room. This situation caused them to not be alert of the light
doorbell notification if they stay in another room because of mobility issue. The project
objective includes the development of the wearable doorbell notification and evaluation
of its reliability based on its functionality and network performance. There is two types
of experiments were conducted in this project, functionality test and network
performance test. These experiments have been divided into a few parts. The results
shows that the higher the RF power amplifier used by nRF24L01, the higher the distance
that can be reached by a signal from the doorbell to the wearable. It also shows that the
data transmission rate did not influenced the response time of the wearable. The
recommendations for future research were to fix the problems in the wearable and create
a wearable alert device with more alarms such as baby crying alarm, fire alarm and
vulgar alarm. |
