What is an Accelerometer Pedometer?
What is the difference between PEDOMETERS (pendulum) & ACCELEROMETERS? Pedometers Pedometers work by detecting vertical motion and hip movement. Pedometers count a step each time they detect this vertical change in direction. A horizontal arm bounces up and down inside the unit by either a spring (Yamax Digiwalker) or a hairspring (a majority of other pedometers). Their accuracy is highly dependent on the placement on the waistband and keeping the pedometer vertical is vital. Tilting or wearing at an angle will affect pedometer accuracy drastically, this is particularly apparent in people with waist measurement greater than 100 cm. (tummy tends to hang over the waistband) The best, most accurate pendulum spring-loaded pedometers are manufactured by Yamax Digi-Walker in both the SW & CW series such as the Digiwalker SW700, SW200 and the CW700 with 7 day memory and dual screen.
