Bio-sensor Project 中文

A completed Bio-sensor project including software and hardware solutions; also depending on the following projects:

Bluetooth BLE Firmware project: https://github.com/feelkit/bioModule_NRF52_BLE

Evaluation Tool using LabWindows CVI : https://github.com/feelkit/bioDemo_labwindows_cvi

Introduce

The project includes a Bio-module(BIO-M001A), an evaluation board designed for the Bio-module, and software solutions including Bluetooth BLE firmware and desktop/mobile evaluation tools.

Bio-M001A is a Bio-module in healthcare;The Bio-module measures and transfers various types of bio-data including ECG, RESP, GSR, HR, PPG, HCM and BIA etc, integrated Bio-Processor with Analog Front-End to make an all-in-one health monitoring solution. The algorithm core runs in Bio-Processor,including SPO2,motion recognition,dynamic heart rate monitoring, trend analysis of blood pressure, Emotional and mental stress etc.

The evaluation board supports Bluetooth BLE with NRF52832 chipset from NordicSemi.

The software solution includes Bluetooth firmware for NRF52,desktop evaluation tool about LabWindows CVI; We are also developing APK for ANDROID, which will be released and open-source .

Bio-Module : M001A

image The Bio-module integrates red (660 nm), green (520 nm) and infrared (940 nm) three-color LED and photodiode(PD) sensor to realize PPG-related applications; and supports four electrodes to achieve applications with human electrical activities and impedance activities; on-module 14-bit three-axis Gsensor for motion/sleep applications.

The Bio-module hardware interface supports SPI/I2C/UART optional, FPC connector reference DF37NB-30DS-0.4V.

Development Kits for Bio-M001A

image The evaluation hardware includes Bluetooth mainboard, pin-board; software includes Bluetooth BLE firmware, PC / mobile APP. How to use the evaluation board, please refer to user's manual.

Bluetooth Mainboard

The Mainboard supports Bluetooth BLE with NRF52832 chipset from NordicSemi,using optional SPI/I2C/UART connecting the Bio-M001A;it communicates with APP via Bluetooth BLE. PC tool connects it by Uart. For the details,please refer to user's manual

Pin-board

The Pin-board is used to turn FPC interface of Bio-M001A into a common open-source hardware interface (xRDUINO UNO), to support more mainboards from other suppliers.For the details,please refer to user's manual

Bluetooth Firmware

For the details,please refer to the project:https://github.com/feelkit/bioModule_NRF52_BLE

Evaluation tool

For the details,please refer to the project:https://github.com/feelkit/bioDemo_labwindows_cvi
