Introduction
samsung health sensor sdk health platform is preloaded in the galaxy watch, which runs wear os powered by samsung its version updates are available through galaxy store or google play samsung health sensor sdk provides tracking for the watch’s raw or processed health sensor data through health platform accelerometer, body composition, electrocardiogram ecg , electrodermal activity eda , heart rate, multi-frequency bioelectrical impedance mf-bia , photoplethysmogram ppg , skin temperature, spo2, and sweat loss data can be measured with the sdk especially, the galaxy watch’s bioactive sensor runs three powerful health sensors including optical heart rate, electrical heart signal, and bioelectrical impedance analysis sensors samsung health sensor sdk enables a wear os application to track health sensor data by importing the sdk’s library samsung-health-sensor-api aar and setting an event listener to receive data events on-demand data tracking gives a one-time data measurement to the application continuous data tracking sends periodical events until the event listener is removed the measuring frequency and number of retrieved health data in each event are different depending on the tracker type the sdk’s main features are capabilities samsung health sensor sdk provides a list of available tracker types for the watch measuring watch’s health sensor data a partner application using the sdk can measure the health sensor data of the galaxy watch the following tracker types are supported [continuous tracking] the following tracker types can be measured continuously until the tracker type’s event listener is unset the continuous tracker types operate with low galaxy watch battery consumption accelerometer electrodermal activity eda heart rate including inter-beat interval ibi photoplethysmogram ppg green, red, and ir skin temperature [on-demand tracking] the following tracker types are on-demand tracker types use only one on-demand tracker type at a time and only when needed bioelectrical impedance analysis bia electrocardiogram ecg multi-frequency bioelectrical impedance mf-bia ppg green, red, and ir skin temperature spo2 blood oxygen level [other] measuring the user’s sweat loss amount after running is available with the following tracker type sweat loss developer mode health platform supports the developer mode for application testing and debugging see health platform’s developer mode for more information target device the samsung health sensor sdk is supported on the following watch devices that run on wear os powered by samsung galaxy watch4 series and later models sdk content content description documents programming guide and api reference library tracking library of the samsung health sensor sdk import it in your app project - samsung-health-sensor-api aar sample apps measure blood oxygen measure blood oxygen and heart rate heart rate tracking with the off-body sensor transfer measured heart rate to a connected phone ecg monitor measure skin temperature sweat loss monitor limitations the emulator is not supported data measured by the samsung health sensor sdk is for fitness and wellness information only, not for the diagnosis or treatment of any medical condition glossary glossary description bia bioelectrical impedance analysis bioactive sensor a 3-in-1 sensor that uses a single chip embedded in the galaxy watch ecg electrocardiogram eda electrodermal activity health platform preloaded in the galaxy watch running wear os powered by samsung it provides the health tracking service to measure health sensor data health tracking service helps to connect a wear os application and health platform and to measure the watch’s health sensor data ibi inter-beat interval mf-bia multi-frequency bioelectrical impedance ppg photoplethysmogram samsung health sensor sdk enables an application to measure health sensor data on the galaxy watch running wear os powered by samsung raw or processed data is retrieved by setting an event listener for each tracker type a partner application imports the samsung-health-sensor-api aar sdk’s library and can track the watch’s health sensor data
