Our prototype collects pressure data from the inflatable arm cuff, and passes it through an instrumentation amplifier and two bandpass filters, then the Arduino Uno collects the data for processing. Currently, the Arduino is connected to a computer via USB to view the data to facilitate the prototyping process, but eventually Bluetooth capabilities will be added to the final prototype.
Signal processing is achieved by the circuit that filters the noise and software coding based on ocillometric method to make our device more accurate.
Prototype Support Android system 8: Display data, storage Data and transfer Data.
Arduino UNO is used as the microcontroller for data collection.
