MEMS (sensors)

What is Nonlinearity (Range: +/- 16g) of the IIS2DLPC acceleration sensor ? Cannot find in the data sheet of IIS2DLPC.

LSM9DS1 BDU Details

Hi everyone,Does the block data update mode block also the sensor's sampling? Or simply the sensor continues to acquire and the registers are just not updated until the next reading? It's very important to me because I use LSM9DS1 gyroscope and accel...

What is the best configuration for saving current consumption when making IOT sensor nodes with lis3dh sensors?

We made a very simple becon sensor.It would take about 25 micro amps to be a pure becon without the vibration sensor.In a vibration free environment, it takes 35 microamps to measure vibration using the lis3dh sensor.It is the ideal current consumpti...

VL53L0X: I would like to use the RANGE IGNORE THRESHOLD but don't know what value to start with. The documentation states N x Xtalk Mcps/spad, where N = 1.5 by default. However I do not use Xtalk. Any idea on how to obtain a useful starting value?

Burst Reading the LSM6DSM FIFO

I am reading the LSM6DSM FIFO with the accel and gyro enabled. I burst read 12 bytes using the SPI. One output byte to say to read the fifo then 12 input bytes (6 bytes of accel and 6 bytes of gyro). That works great. I tried reading more than 12 byt...

Can't vary duration on LIS3DH fall detection

I have been trying to setup fall detection interrupt on LIS3DH. I can get it to work but only with specific setup. In particular INT1_DURATION values: 0x05 works (but is too short) so my global setup is ok. But with any other duration values, even ju...

VL53L0X problem connecting to Nucleo F401RE

HiI have been working with the Nucleo F401RE + P-NUCLEO-53L0A1 sampling the VL53L0X, and it was working fine. However interfacing the Nucleo F401RE  to another VL53L0X module (https://picclick.de/VL53L0X-Time-of-Flight-Distance-Sensor-Breakout-GY-VL5...

Using DHT22(AM2302) sensor

Hi,I'm looking for some example how to use the sensor with STM32 and wonder why all of them, which I've found, are based on the loop not on interrupts.The response is 40 bits and it takes up to several milliseconds to read it, so during the time MCU ...

MEMS Microphone to STM32H7 for acoustic analysis device: SPI / I2S, SAI or DFSDM ?

I am developing a device which needs to continuously monitor noise (buffer / page to memory) and either Once or 8 Times per second analyse the acquired data to provide the following:FFT CPB (single or 1/3rd octave band analysis)Various over-all and ...
