How Fitness Sensors Work

Fitness sensors usually come in the form of smartwatches. They sit on your wrist and they track your steps and even your heart rate. They also calculate the steps that you take based on your speed. For example, whether you are running, doing a light jog or even a sprint. That brings about the question, how does your fitness tracker know all of this stuff?

Daily Steps
Fitness trackers usually come with a 3 axis accelerometer. This helps you to track movement in every single direction you take. Some of them even come with a gyroscope as well. This helps you to measure the orientation and even the rotation of how you move. All of this data is collected and it is then transferred.

The data is used to calculate the calories that you have burnt the quality of those steps and more. It is true that there could be some guesswork involved but the end result is usually pretty accurate. Some watches even come with an altimeter as well. This works by measuring the altitude that you are walking at so that you can measure how many calories you have burnt walking up a mountain as opposed to walking on a straight plane.

An In-depth Look into Fitness Watches
The future is now here. Some watches come with a temperature sensor and this helps you to check how resistant your skin is. Others use a sensor which shines a light onto your skin and this also helps to measure your pulse as well. When the light is shone on your capillaries, the sensor then measures your heart rate and even the rate at which the blood is being pumped through. The sensors are far less effective when it comes to judging your overall health, but they are incredibly useful, to say the least.

Sleep tracking is called actigraphy and this works by translating your wrist movements into sleep patterns. Again, this does include some guesswork but it is a brilliant way for you to try and find out how easy it is for you to get a good night’s sleep.

Ultimately, wristwatches and smart fitness devices work in different ways but at the end of the day, they can really help you to understand your own body and how it works as well so do keep that in mind when the time does come for you to get started.
