Smartwatches have come a long way since their inception in terms of fitness and health-tracking features. Most smartwatches are able to perform a lot of functions because of the sensors that come fitted in them. A smartwatch typically includes a variety of sensors to enable its many features. The five main sensors in a smartwatch are an accelerometer, a gyroscope, a heart rate monitor, a GPS, and a barometer.
These sensors work together to provide a wide range of features and functionality, from tracking fitness and activity to providing notifications and location-based services. Almost all smartwatches can also be paired with smartphones, allowing users to receive calls, messages, and other notifications on their wrists. Additionally, many smartwatches include a variety of apps and features, such as music controls, voice assistants, and mobile payments, making them versatile and convenient devices. Here we explain what these sensors do:
Accelerometer: To calculate steps, calories burned and more
An accelerometer is a sensor that measures acceleration or the rate of change of velocity. In a smartwatch, the accelerometer is used to track movement and activity, such as steps taken, distance travelled, and calories burned. It also enables features such as wrist gestures and shake-to-wake.
Gyroscope: Helps in counting steps among other things
A gyroscope is a sensor that measures angular velocity. In a smartwatch, the gyroscope is used to track the orientation of the watch, enabling features such as screen rotation and step counting.
Heart Rate Monitor: To keep track of heart health
A heart rate monitor is a sensor that measures the wearer’s heart rate. In a smartwatch, the heart rate monitor is used to track fitness and activity, as well as for monitoring for signs of stress or other health issues.
GPS: Tracking runs and location-based features
A GPS sensor is a sensor that uses signals from satellites to determine the device’s location. In a smartwatch, GPS is used to track the location of the wearer, and to provide location-based services such as turn-by-turn directions, tracking of runs and bike rides, and location-based notifications.
Barometer: Measuring altitude among other things
A barometer is a sensor that measures air pressure. In a smartwatch, a barometer is used to measure the altitude, provide weather forecast, and track the changes in elevation while climbing or hiking.
