MEMS (sensors)

I am performing the self-test for the LIS2DW12 accelerometer. For some axes, when I compare data with and without the self-test enabled, I am getting a large difference in acceleration. Do I need to account for buffer overflow?

For example, given the following data taken from the sensor should the Y reading marked with a * account for a buffer overflow and therefore the difference be calculated as follows: 0xffff - 0xffd4 + 0x0e88 = 0x0eb3Initial X Reading:        0x0068Se...

Hi i need help. I have a B-L475E-IOT01A with a sensor vl53l0x. I try to use the library img005 but i'm not able to read with this the distance by the sensor. Someone have an example of main to do it? I have also difficult with the vl53l0x platform lib

I want to decrease the power consumption of LIS2DW12. It proposed to sense human motion, and I don´t know if it is better to have a Low Pass Filter or High Pass Filter configured in CTRL6, and what LPM mode I should set in CTRL1. Please see details below:

Actually our device has 33 uA in DC current consumption without accelerometer LIS2DW12, with the LIS2DW12 this previous number increases to 55 uA.I think that it is possible to decrease the current consumption, based of the information of datasheets....

Are there any application notes on using H3LI5331DLT for shock detection? Peak shock detection?

Do all current consumption of lis2mdl tested in 2.5V?

In the spec, Table 10 and Table 11 show's the current consumption when LIS2MDL working in different modes. But it doesn't verify the test voltage. Please help to confirm if they were measured in 2.5V. Thank you!

Problems with temperature affecting the readings from LSM6DS3TR.

I'm developing a product using the LSM6DS3TR. As per the data sheet the data from the device should not be influenced by temperature more than 1.5% between -40 and +85 degrees. I see wild swings in the data for the Y-Axis Accelerometer when the tempe...

LIS3DH using too much power on custom board

I have a custom board that includes the LIS3DH. With the LIS3DH not populated, my board uses 0.009mA, but with the LIS3DH populated and not configured, it uses 0.135mA. According the data sheet, it should be 0.011mA. The data sheet also says the LIS3...

Why is the LSM9DS1 magnetometer X and Y sensitive to mechanical stress?

Hi,we're using the LSM9DS1 as the basis for a compass. We have found that the magnetometer X and Y axes seem to show a huge sensitivity to mechanical stress. if you apply a slight bending stress (just with your fingers, nothing special!) to the pcb, ...

hts221

When the hts221 passes the test, the humidity of the constant temperature and humidity box is adjusted to above 70% (the temperature of the constant temperature and humidity box is not set to a specific degree), which is very inaccurate.In particular...

IIS2DLPC wake up interrupt bit always set?

it seems that the status bits in the registers for wake up are always active - Is it possible to remove them? If I setup the part to wake up routing the wake up to INT1, then issue a soft reset to the device, setting it up next to just route the DRDY...
