VL53L0X spurious readings noted when kept on floor

I am using VL53L0X for distance sensing with a PMMA (acrylic) glass cover of 0.6 mm on it at an distance of 0.4 mm. When i keep the sensor on the ground and try to get the distance measurement when there is nothing but the roof in front of the sensor...

I am trying to find out the pin configuration done for Mic in STM32F446RE-Nucleo.As per the schematic PB5 must used for MIC_CLK and PB15 for MIC_PDM12_OB. But i'm not getting where the Pin configeration for Mic is done?

I am using STM32CubeFunctionPack_SMARTMIC1_V1.1.1 project.FP-AUD-SMARTMIC1https://www.st.com/en/evaluation-tools/steval-bcnkt01v1.html#sw-tools-scroll

Problem with the iis328dq's data ready interrupt

I'm trying to read the data from the iis328dq using the data ready function.To do so, I wrote the CTRL_REG1 with 27h and CTRL_REG3 with 82h to have the accelerometer working in normal mode with 50 Hz of ODR. I use SPI at 25 Mbit/s to comunicate with ...

Temperature readings on the LIS2HH12TR

Can anybody suggest why I am getting a fixed 10 C colder offset from the temperature reading for this accelerometer?

Did the accelerometer LIS2HH12TR have precision to sense a g-variation in the fourth decimal ? I can't see anything about it in the datasheet. It also has this precision in the following temperature range: -10 to 50ºC Kind regards, JGF

LPS22HH I3C Address Assignment Collision

I'm working on a new design requiring four pressure sensors. The LPS22HH only allows two I2C address's through pin 5. Rather then increase complexity by putting all four on SPI I wanted to see if I could use the I3C bus capability. The datasheet refe...

STEVAL-MKI015V1 with STEVAL-MKI109V3 and Unico 7.0.0.0

I'm trying to evaluate STEVAL-MKI015V1 with STEVAL-MKI109V3 and Unico 7.0.0.0. The device appears in the selection menu, but I got the error "Device is not supported by the motherboard". I successfully completed the firmware upgrade through DFU (curr...

LPS22HD uses the package HLGA-10. What is the thermal coefficient (Rja) of this package? Where can I find the thermal data?

​The LPS22HD  data sheet does not contain thermal information

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
