Accelerometers
Accelerometers measure acceleration forces in one or more directions. They can detect changes in velocity, tilt, vibration, and shock, providing valuable data for motion sensing, orientation detection, and vibration analysis. These sensors typically use microelectromechanical systems (MEMS) technology or piezoelectric elements to convert mechanical acceleration into electrical signals.
Generally, accelerometers with higher measurement ranges, greater sensitivity, and higher accuracy levels are priced higher. The choice between analog and digital output interfaces can also influence pricing, with digital accelerometers often being more expensive due to additional onboard processing capabilities.
When purchasing accelerometers, determine the measurement range and sensitivity required for your application, ensuring that the accelerometer can accurately capture the acceleration forces of interest. Additionally, assess the output interface compatibility with your system, whether analog (voltage or current output) or digital (SPI, I²C, UART), and choose accordingly based on your communication preferences and integration needs.
