MEMS (sensors)

Hi, we want make meassurements around 10uT using the sensor LSM303D. The measurement is static, so f=0. Which uncertainity we have to expect such as gaussian noise etc.? Thanks...

What is the SA0 behaviour of LIS331DLH with floating SDO pin?

The LIS331DLH language is slightly different regarding the SA0 function, compared to the LIS331DL. The LIS331DL datasheet explicitly states that the SDO pin can be left floating and SA0 will be treated as a '1': "The slave address (SAD) associated w...

Algorithm to calculate Vibration.

Hi,We are using LSM303AGR in our product and I am able to derive X, Y and Z axis G values.Now I want to calculate vibratio based on X, Y and Z values.What is the algorithm to calculate vibration using X, Y and Z values.Do you have any white paper or...

STEVAL-BFA001V1B FFT results

Hello Sir/Madam, We are validating STEVAL-BFA001V1B on motor for condition monitoring. Motor is rotating with 1500 RPM speed , when I observe the FFT results , rotating frequency 1X is coming around 26Hz when my settings are ODR- 6660Hz (also with 3...

STEVAL-MK1175V1/LIS2DE12 accel setup help

Hi, I'm using the LIS2DE12 as a motion detector for my nRF BLE product. I purchased the eval module (STEVAL-MKI175V1) and I'm trying to set it up over SPI from the nRF52 eval board. I followed the datasheet for the eval board and connected the basic ...

Can we "deGauss" the LIS2MDL using register commands to reset the AMR when exposed to high field to remove large hard iron offsets? The MMC5983MA allows this, does the LIS2MDL?

We have noticed that several LIS2MDL have come back to us with very large magnetic field offsets. While these can be corrected by the usual offset calibration, the large offsets are due to exposure to a large magnetic field source somewhere in the en...

Getting unexpected I2C Slave Address from a LSM9DS1 sensor and reading the wrong data from the register I just wrote in

I am using a STM32F030R8 nucleo board and a LSM9DS1 sensor. I'm just starting out learning about this stuff and I am having troubles reading from the sensor. Here are all the details about the problem I am having. I initialized the peripherals and th...

LIS2DW12 does not respond with ID the first time

When the LIS2DW12 is asked for the first time for ID it does not response(responses with 0xFF).The second time responses regularly with 0x44. Enclosed are SPI signals for the first try.

the gerber files of STEVAL-MKI181V1 is wrong , the pin map is for LIS3MDL, not LIS2MDL , please check
