What is the accelerometer step -meter?

The

Accelerometer is one of several types of equipment that calculates the number of steps carried out by the carrier or by measurement of vertical movement. Perometer are excellent tools to monitor activities and to motivate users to increase the level of activity. Studies on pedometers have shown that their use increases physical activity, reduces body weight (BMI) and lowers blood pressure levels. Compared to other types of exercise devices, pedometers are cheap, reliable and easy to use. This design uses the horizontal arm of the lever suspended from the spring that moves up and down when the hip users accelerate during step. The movement of the lever arm opens and closes the electrical circuit that registers the step. Another similar mechanism uses a magnet at the end of the lever to introduce a close switch to register this step. Pendulum pedometters maclinking on the sound as the shoulder moves and the steps are calculated.

The internal stemometer mechanism of the accelerometer uses the piezoelectric crystal as part of the voltage breakup that generates the voltage in proportion to vertical acceleration. This type of mechanism is more resistant and usually lasts longer than the spring mechanism. The accelerometer pedometers also offer a significant advantage in measuring rather than simply register vertical movement and can measure the intensity of activity in addition to counting steps. Another advantage is that the accelerometer stepometer mechanism is silent and does not release clicks when counting steps.

The padem's pendulum must be kept in a vertical vertical position so that the spring mechanism works properly, and usually wears cropped into the waist. Loading or carrying at an angle can affect accuracy by up to 25 percent or more, depending on the model. It turned out that the accelerometer pedometers are significantly more reliable and accurate. Depending on the model, they can be accurate up to 1 percent. Perometer with sensors with double AKThe celery is not sensitive to the tilt and can be transmitted in a pocket or handbag or worn on an ankle strap.

Simple pendulum perometer can be very cheap and are often distributed free of charge in promotion and awareness programs. A more sophisticated pedometer of the accelerometer can cost more than $ 100 and will usually have other features such as calculating the distance and estimate of the number of calories burned. The sensitivity of the internal device is another important factor when one considers different models. Pedometers tend to overestimate the number of steps by counting other movements, such as the bearer who moves his body while sitting. Perferences of better quality will include a routine that registers, and the steps are made until a minimum threshold number of steps has been achieved, helping to prevent overlap.
