With digital products evolving at a continuous rate, many devices today primarily rely on internally installed sensors to operate. The application of this technology spreads across various fields, ranging from: smartphones, tablets, smartwatches to VR glasses, drones, automotive assistance systems, and smart devices for Industry 4.0 applications. Integrating sensors has enhanced these products, making them increasingly intelligent.

About Accelerometers

An accelerometer, a type of sensor, is primarily used to either capture relevant numerical information about the motion of objects or to measure their posture. It is an electronic component, aka an inertial sensor, that is composed of the following two elements:

  • Accelerometer
  • Gyroscope

An accelerometer is typically a component that measures acceleration, including both motion acceleration and the gravitational acceleration generated by the Earth. When the sensor is in free fall, the motion acceleration precisely cancels out the gravitational acceleration, resulting in an output of 0. This is commonly expressed in units such as, ‘g’ or ‘m/s^2’.

Accelerometers are common applications within a wide range of technological devices, such as: smart devices, pedometer apps, sports watches for running, and game controllers. In the automotive industry, accelerometers are used to detect and assess the stability and deviation of a car’s speed during driving. This extends to features like  safety airbag systems, inertial navigation, emergency call systems, collision identification and recording systems, dash cams, in addition to smart brake lights for bicycles; technology widely recognized by the public. Hence, reliance on its quality and efficiency are essential for product consumers.  

Why We Need Accelerometer Testing

Issues commonly encountered with accelerometers are capable of leading to usability problems in affiliated products. If not addressed in early stages, it may result in a subpar user experience, significantly impacting the brand’s image as well as user safety. Here are five risks identified by Allion:

  • Large Numerical Error in sports monitoring
    Pedometers and other monitoring functions are inaccurate; affects consumers’ judgement of their exercise conditions. ’


  • Games screen experiences significant latency
    Latency issues cause inconvenience while players use VR goggles for gaming.
  • Low accuracy of the health monitoring feature
    Health-related monitoring functions may provide inaccurate readings or convey incorrect health information. This leads to a potentially severe risk of users misinterpreting their condition , which is capable of leading to health hazards.
  • Image integrity of the dash cam
    Collision detection triggering fails, preventing the faithful restoration of the scene’s image at the time of the incident; leads to the overwriting of the accident footage.


  • Failure to activate smart brake light of bicycle
    The emergency lights fail to activate during braking, causing bicycles to be unable to signal vehicles behind them; capable of resulting in rear-end collision.


Conducting accelerometer sensor testing not only enhances the stability and reliability of the accelerometer sensor, ensuring the product’s flawless functionality, but also instills trust in users regarding the stability and precision of the accelerometer sensor. Allion is capable of assisting you in the overall product development process, saving time and money in addition to reducing implementation expenses.
