Accelerometers Shopping Guide

Accelerometers are a great tool for assessing the movements and vibrations of your body. If you are a beginner looking to purchase your first accelerometer, there are a variety of options to choose from. Here is a shopping guide to help you begin your search:

Determine what type of accelerometer you need. There are three main types of accelerometers: piezoelectric, capacitive and micro-electromechanical (MEMS). Piezoelectric accelerometers are generally the most accurate and can measure very small vibrations. Capacitive accelerometers are more economical and can detect large vibrations. MEMS accelerometers are relatively low cost and have good precision.
Choose an appropriate range of measurement. Accelerometers typically measure three axes: X, Y, and Z. The range you purchase should be able to measure the type of vibrations that you want to detect.
Consider the frequency range you need. The frequency range is the range in which the accelerometer can detect vibration. You should purchase one with a frequency range appropriate to your application.
Look at the output type. Accelerometers typically produce either analog or digital output. An analog output will require extra hardware to convert it to digital format. A digital output can be read directly into a computer.
Think about additional features to look for. Many accelerometers include features such as temperature compensation, on-board filtering, and the ability to interface with other devices.

These are a few of the factors you should consider when purchasing an accelerometer. With this guide, you should be off to a good start finding the best accelerometer for you.
