Adxl345 noise , x and y axis are changing constantly

[arpa123]

I have an ADXL345 accelerometer connected to an ESP32. However, even without any movement or touch, I observe significant fluctuations in the x and y axis readings.

I've tested using both 16g and 2g settings, but encountered the same issue. My objective is to detect any movement of the object (e.g., if someone touches and tries to move it) and trigger an alarm based on the information provided by the accelerometer."

I observe significant fluctuations in the x and y axis readings.

Most likely, that is the expected sensor noise. To detect movement, the acceleration must exceed the noise level.
