MEMS (sensors)

I design a battery powered BT Tag using LIS3DE. I want to detect movement as a trigger to transmit BT beacons. Which mode should be choose if I want to reduce the power consumption.

LIS3DE connects to BLE IC using I2C Bus and INT pinsPlease state the mode according to time before and after the trigger.Second, if I want to monitor 30 seconds after trigger to double check is it need to transmit BT beacons. May I use LIS3DE FIFO to...

Sensor fusion for accelerometers >+-16g scale

Hi,Does the iNEMO sensor fusion tool work with accelerometers with larger than +-16g output

IIS328DQ will this accelerometer works for slow movements or constant movements?

My Requirement:I want to get the data if there is a angle change more than 5 degrees in any direction(X , Y , Z)  and it should work for very slow movements or linear or constant movements. Will this sensor works as per my requirement or not. Please ...

How do I remove temperature compensation from accel and gyro signals for the LSM6DSM?

MotionFX: Different between implementation for M0 vs. M3

Hi,i am trying to use the MotionFX library on M0 MCU for LSM9DS1. As result i read the rotation_9X structure and use yaw as heading for compass result. The result showing the rotation but i see the offset on the Z axis of the gyro and the heading res...

What are the units for the "output data rate of 5.3kHz? How long does the LIS2DE12 take to fill its FIFO.

The datasheet gives an "output data rate" for this sensor of 5.3kHz. What are the units on this, bits, bytes, 16-bit per-axis words, or for each complete set of 3 X, Y & Z data samples? Is this the output of internal sampling, the fifo fill rate (uni...

On an LIS3DH in low power with FS set to +- 16g the datasheet on page 10 gives a sensitivity of 192 mg/digit. So 192 * 128 = 24,576. Or a range of 24.6 g??? Am I missing something???

Is there limitation for SPI address auto-increment option in LIS3MDL devices?

Hi All,I can read successfully in burst mode "MS bit is set to '1'" the data from output registers X_L, X_H, Y_L,Y_H,Z_L and Z_H.But if i add temperature data TEMP_OUT_L, TEMP_OUT_H into read frame the temperature value is not read.Examples: Rx buff...

Cannot access mag registers on LSM9DS1

On about 15% of the boards in my latest production run I am able to access the accel/gyro registers over the I2C bus but cannot access the magnetometer registers. As a simple test I am trying to read the WHO_AM_I register (0x0F) for both. I get the...
