BMI160 UltraLowPower "Out of Bed" detection

[Wela]

Hi Community,

I am trying to implement an ultra low power  version of an out of bed detection. I do not want to use interrupts.

Is there a way to set the sampling rate lower than 0,78125 Hz, or is disabling and re-enabling the only solution? Sample rate of about 5sec would be great. Because I want to calculate the average of 30 sec and send it to the smartphone.

Kind Regards,

wela

The current lowest ODR supported by our acceleration sensor is 0.78Hz. 

If you need even lower ODR,  i will suggest you to set sensor to suspend mode, then wake up sensor manually by system timer, after getting some data then set to suspend mode again.
