Raw PPG Signal Measured Using Wearable Sensor-kit in Varying Levels of Activity

<p>This data is part of the <em>Wearable Sensor-kit to Characterize Affect</em> project. It was measured using an Arduino-based wireless, wearable device that consists of several biosensors attached to a wrist brace. It was designed and built for the purpose of measuring students' biometrics. </p>

<p>The PPG signals were measured using <em>Asiawill Pulse Heart Rate Sensor Module</em> from the ring finger of the left hand for five healthy participants in three scenarios that vary in the level of activity. In the first scenario, the participants were asked to sit as still as possible while resting their left hand (with the sensor-kit) on a table. In the second phase they were asked to talk about a topic that they already know and are passionate about. The purpose is to introduce motion artifacts from communicative gestures. Lastly, the participants were asked to walk to introduce motion artifacts from movement. Each phase was about 10 minutes long.</p>
