Why dose VL53L0 measure anormal value after a long time?

I use Arduino Uno and VL53L0 sensor appliction board.I measure a distance long time. (8h or more) But after some time(maybe after 1h or more), it measure distance but it is anormal.for example, normal status distance is 100-120mm, but after some tim...

How to disable Readout protection in the Steval-BCN002V1(BlueNRG) sensor?

Hello, I'm trying to flash a program on Steval-BCN002V1(BlueNRG) sensor with NUCLEOf446RE using STM32CubeIDE. I'm facing an issue related to read out protection. I'm not able to disable the read out protection using STLink utility (Menu-> target->o...

I am looking for the azimuth (heading) algorithm used in the UNICO demo software for the LSM303AH eval board. When I use the AX, AY, AZ, MX, MY, MZ data from this sensor and apply an AZ algorithm, I don't get the same answer as the UNICO.

HTS221 Temperature measuring

Hi,we are using HTS221TR. In the datasheet it is not clear what is the temperature range what the sensor can measure -40...85? +15°C....40?

Hello Team, We would like to confirm the current consumption of the LSM6DS3USTR while enabling the Accel+ Gyro Mode.

We are in middle of our Production process and we are using your LSM6DS3USTR. Here are the setup we have :1. combo mode (i.e Accel+gyro) 2. ODR = Accel(26Hz) and Gyro(26Hz). 3. Input power supply = 1.8V Currently, we are seeing a constant current pul...

Skew between samples of acceleration components in sensor IIS3DHHC

Hi guys,I would like know is there is any skew between the acceleration samples of each axe, i.e. ax, ay, az. In other words, if the acceleration components (ax, ay, az) are sampled at the same instant or in sequence. In this last case, I would like ...

Software reset of VL6180X sensor.

Hello,I have multiple VL6180X sensors which are handled by i2c multiplexor. Once I power up the sensor and configure it I can get measurements, but after MCU reset or switch the power I cannot get new measurements anymore. And the same problem with a...

LIS2DH12 Direction Recognition Interrupt

In the datasheet, for the INT1_CFG register, it says:AOI-6D = ‘11’ is direction recognition. An interrupt is generated when the orientation isinside a known zone. The interrupt signal remains while the orientation is inside the zone.I want to be able...

Use LSM6DSO to detect free-fall event can not work!

According to the official sample program, I set the register to detect free-fall event,But it can't be detected very well, even when I haven't moved anything, I have always detected the free-fall event,How can I use lsm6dso to detect free-fall event ...
