This health sensor band platform is a wrist-worn wearable form factor that demonstrates the high sensitivity and algorithm processing functions for health-sensing applications. It includes an enclosure and a biometric sensor hub with an embedded algorithm for heart rate and SpO2 (blood oxygen saturation) which processes PPG (Photoplethysmography) signals from the analog-front-end (AFE) sensor. Algorithm output and raw data can be streamed through Bluetooth to an Android app or PC GUI for demonstration, evaluation, and customized development.Includes: * Micro board * MAX32630 microcontroller * MAX20303 power-management IC (PMIC) * Dual-mode Bluetooth® connection * Tri-color status LED * Sensor board * MAX86141 analog front-end and optical heart rate sensor with one green LEDs, one red LED, one IR LED, and two photodiodes * MAX32664 microcontroller with embedded heart-rate algorithm * Three-axis accelerometer * MAX4740 quad SPDT switch which, in combination with the MAX86140/41, enables different LED and PD configurations * One green LED, two combination RGB LEDs (One of these RGB LEDs is currently not used by the algorithm. The extra LED is reserved for future use: To simplify the design, the extra LED and the MAX4740 may be removed for the heart rate, SpO2 use case.) * MAXDAP Pico Adapter board to be used during a firmware upgrade for the micro board * Two USB Micro-B cables for firmware upgrade of the micro board or for PC communication with the micro board or charging of the health sensor band * Health sensor band enclosure * Battery * One USB Type-C cable for PC communication with the micro board (Windows 7 or Windows 10) or charging of the health sensor band Additional requirements: * PC (Windows 10 only) with Bluetooth connection for data streaming and logging * Android device with Bluetooth connection for data streaming and logging https://elecena.pl/product/16991024/wrist-based-spo2-hr-and-hrv-health-sensor-platform 2020-06-26 https://elecena.pl/product/16991024/wrist-based-spo2-hr-and-hrv-health-sensor-platform 2020-08-04 https://elecena.pl/product/16991024/wrist-based-spo2-hr-and-hrv-health-sensor-platform 2021-07-28 https://elecena.pl/product/16991024/wrist-based-spo2-hr-and-hrv-health-sensor-platform 2022-08-30
