Difference Between Accelerometer and Pedometer

Ever wonder what’southward the difference between a pedometer and an accelerometer? A pedometer is a step-counting electromechanical device that, as the name suggests, counts the number of steps taken in a given time. An accelerometer is a more than advanced pedometer that also records your speed and distance. For further information, go on reading the article.


What is an Accelerometer?

An accelerometer (or acceleration sensor) is a device that is used to measure out acceleration, the rate of modify of the velocity of an object. Accelerometers are the most widely used vibration sensors that convert mechanical forces such equally vibration, motility and shock into electrical signals that can be measured and recorded. Accelerometers are the commonly used sensors implemented in MEMS (Micro-Electro-Mechanical Systems) engineering science. These sensors can be used in a variety of settings and come in different types, ranging from a elementary handheld device to full-fledge space stations.

Accelerometers are used across a wide range of application areas, such every bit automotive industry, aviation, aerospace engineering, biological engineering science, etc. In fact, at that place’s a good gamble you already have a device with an accelerometer in it. For instance, your smartphone has an accelerometer embedded in it which helps notice the orientation of the phone, meaning it detects which direction the phone is pointing. They are besides institute in fitness trackers which help runway movements of the body. The primary sensing mechanisms include capacitive, piezoresistive, piezoelectric, and resonant types.


What is a Pedometer?

A pedometer is a uncomplicated pace-counting device that measures the number of steps takes in a given time and calculates the gauge number of calories burned. Information technology is a portable, beeper-sized device that detects the vertical movement of your hands or hips, thereby counting each step by detecting the motion. It can be a good motivational tool for practice and is typically worn at the waist. It tin can besides exist worn in the arm or ankle. As you motion, the device acts like a pendulum on a wall clock that swings dorsum and forth according to the motion of your hips.

Annotation that the altitude measured by a pedometer is based on the number of steps taken and the stride length fix in the device. All the same, they also detect movements other than walking, such every bit tying your shoes, leaning motions, shaking your booty, etc. So, do non expect complete accurateness. In addition, spring-loaded pedometers have the tendency to underestimate the number of steps taken at a slow stride. So, for all-time accurateness, you should attach the pedometer on a chugalug or waistband directly to a higher place a leg.

Difference between Accelerometer and Pedometer

Part

 – A pedometer is a portable, beeper-sized device that measures the number of steps takes in a given time and calculates the guess number of calories burned. It is typically worn at the waist but can also be worn in the arm or talocrural joint. It senses your body movement and records your steps. An accelerometer is a more advanced pedometer that measures the rate of change of the velocity of an object (acceleration). Accelerometers are too called piezoelectric pedometers.

Working

– Accelerometers work past sensing the acceleration of gravity or acceleration of motion. The force acquired by the vibration or motion causes the piezoelectric cloth to squeeze, which in turn creates an electrical charge which can be measured and recorded. A pedometer uses a mechanical sensor to calculate a user footstep based on the dispatch fluctuations throughout the walking cycle. You can monitor the length of your usual stride which you can convert into distance.

Usage

– Pedometers are wearable devices that monitor the number of steps taken in given period of fourth dimension and are near popularly used as everyday motivational tool and practice progress monitor. To properly use a pedometer, y’all demand to prepare your stride and body weight then that the device can record steps and mileage accurately. Accelerometers are used in a variety of applications including vibration monitoring in cars, biomedical applications, navigation and guidance systems, process control systems, safety installations, smartphones, etc.

Summary

Accelerometers are more than avant-garde pedometers typically used for vibration monitoring in many dissimilar fields, such as automotive industry, aviation and national security, aerospace engineering, and biological engineering. The master sensing mechanisms include capacitive, piezoresistive, piezoelectric, and resonant types. Pedometers are portable wearable devices typically worn at the waist as well as in the arm of talocrural joint. They are used to measure the number of steps taken in a given flow of time and summate the approximate number of calories burned.

Are pedometers more accurate than accelerometers?

Although, pedometers measure steps taken in a given time period and calculates the approximate calories burned, they are non as accurate. They tin can be off past as much as ten% with altitude. Also, pedometers accept the tendency to underestimate the number of steps taken at a slow pace.

Can accelerometer measure steps?

Accelerometers detect movement or motion, and when moved, it calculates dispatch. Accelerometer is an avant-garde pedometer that tin proceed rail of your steps.

What is an accelerometer used for?

An accelerometer is used to mensurate dispatch, the charge per unit of change of the velocity of an object. They are basically vibration sensors that convert mechanical forces such as vibration, motion and stupor into electric signals.

What is an accelerometer in fettle?

An accelerometer is a motility monitor that captures the intensity of physical activeness past taking inertial measurements of velocity and position. Accelerometers can be plant in fitness devices such as activity trackers (eastward.g., Fitbit), smartwatches, and smartphones.
