FYP2 : Week 15

Continue writing Results (Device) 

Objective : 

• To write result based on the objective of the project

• To show the device based from the development of this project

Activity: The main objective of this project is to develop a device that can detect fall signs that happen to the elderly via using accelerometer and pulse sensor. This is the result of the wearable device to detect the fall incident. The device has a box that contain  the components of this project ad a strap attached with it to be wear on the wrist. The box size is 20x6x2.5 cm which is quite compact and the angle of the box is curve and not sharp which is safe for the user. From the front of the device can be seen the battery compartment and antenna of GSM. From the left-side of the device have a cancellation button which to cancel if it a false alarm. Then, from the left-side also have a hole for buzzer sound and  Mini-B USB port for Arduino Nano. From the right-side of the device can be seen the hole for pulse sensor wire as it located under the device box. Besides, it also have on/off switch and a step-down converter. All other components was located inside the box.
