Sensors

NOWATCH is equipped with advanced sensors to continuously capture your physiological data:

• Pedometer

  • It tracks your steps throughout the day, helping you monitor your physical activity. It provides insights into your movement patterns.

• 3-axis accelerometer

  • This sensor measures acceleration in three directions: X, Y, and Z. It tracks how quickly you move in each direction, providing insights into your physical activity.

    • X-axis detects movement from side to side (left to right).

    • Y-axis detects movement forward and backward.

    • Z-axis detects movement up and down.

  • The accelerometer is used to gather metrics such as Motion (i.e., how much you're moving), and Activity Type (e.g., walking, running, etc.).

• Photoplethysmogram (PPG)

  • Uses green, red, and ambient lights - which measure changes in blood pressure by illuminating the skin and measuring changes in light absorption.

  • The PPG sensor is used to measure metrics like Heart Rate (HR), Heart Rate Variability (HRV), Breath Rate and SPO2.

• Proximity sensor

  • It detects the proximity of the device to an object, such as your skin.

  • It helps determine whether the device is being worn, and signals when to activate or deactivate the sensors accordingly.

• Bio-Impedance (BioZ)

  • It is converted into Bio-conductance, which refers to the conductance between the two electrodes (the metal plates at the bottom of the watch that make contact with your skin).

• Temperature

  • It measures your skin temperature. We are currently working on integrating it into the Timeline, enhancing existing metrics like the Stress Gauge, and developing new ones.
