Finding specification of the required components
Objective : To find components specification
Activity : This is part of methodology chapter. I need to find components specification by finding their datasheet and compare which model is more suitable for this project. There are for main components that required in this project are accelerometer, optical photoplethysmogram (PPG) sensor, Adruino UNO and GSM. For accelerometer, ADXL345 was chosen compared to ADXL33 has inbuilt functions such as free fall detection activity. Then GSM module SIM900A
was chosen compared to SIM900 as this project only will use simple function of GSM which is to send alert SMS.
Conclusion : The list of required components are Arduino UNO, accelerometer ADXL345, PPG BH1792GLC and GSM SIM900A was chosen.
