ST LSM6DSL or Invensense MPU-6555 ?

Question asked by moerwald.patrick on Mar 2, 2016
Hi,

we have to chose a accelerometer/gyro combo for our sleep/motion tracking wearable. We have a big focus on energy consumption since the form factor of our wearable device should be exceptionally small and therefore we cannot put in a big battery.

We are unsure if, power-wise, the MPU-6555 is better or the LSM6DSL, if we do 1 Hz sampling of both accelerometer and gyro and the rest of the time put both in the power saving mode.

Can anyone estimate how much average power the LSM6DSL needs when doing 1 Hz sampling of accelerometer and gyro?

Thank you and best regards,

Patrick
