In this Innovation Lab post, vibration is measured using the Evaluation kit featuring A121 sensor and the Exploration tool. Vibration measurement can be utilized to predict maintenance. For example, movement of constructions such as buildings and bridges, and structures such as train tracks are measured and maintained before these infrastructures are going to be damaged or collapse.

Moreover, monitoring condition of industrial machinery can be useful for saving maintenance cost and prevent fault operation. Continuous measurement can be done without stopping machines.

More information regarding vibration measurement can be found on the Acconeer document site.

The video shows that A121 sensor can be used to estimate the frequency content of vibrating object, measured at a distance.


One XE121 Evaluation Board and one XC120 Connector Board are necessary for this implementation.


Flash the Evaluation kit through the Exploration tool. Follow the instructions indicated on the Acconeer GitHub page.

Exploration Tool

In the Exploration Tool, click “Vibration measurement” on the left-side menu, and then click “Start measurement” on the right-side menu to start measuring vibrations.
