LSM303AGR accelerometer disappointing accuracy

I configured LSM303AGR accelerometerit for high accuracy mode 50Hz and I am reading it at 20 Hz via i2c.The xyz signals are very unstable, and the final angle calculated (see figure) has huge variations. 2 degrees is far from what my expectations for...

How to make the LSM6DSOX run ultra-low-power in production environment?

Hello all,I've recently been trying to make the LSM6DSOX run ultra-low-power. However, I can't get it to work. I tried it with the 109V3 dev board in Unico, where I can get it to run at ~15uA. However, when I turn that configuration into a .h (header...

Stream sensor data live to MATLAB with BCN002V1B

Hey all,I bought the STEVAL-BCN002V1B and need for my use case live sensor data of the accelerometer, gyroscope, magnetometer and the data of the senor fusion in MATLAB.I already tried the Unicleo software and the ST BLE Sensor-App, but i only found...

Question from Predictive Maintenance Webinar 29th of April: Energy consumption is really a challenge, is Wifi connection really suited for this application ?

Can I use the SensorTile with a simple 3V power Supply?

I have the SensorTile development kit, where I am able to successfully connect and use the SensorTile with either the cradle or expansion board. What I would like to do is use the SensorTile core board without having to use the cradle or the expansio...

Mechanism of the digital temperature sensor and thermal watchdog.

I'm a studtendt from Beijing ,China. I want to use STTS75, an integrated digital temperature sensor and thermal watchdog in a high-g enviroment(~200g). Could someone tell me how the sensor works and its capabilty of bearing high acceleration? Pape...

LSM6 gyro reading drifting even though stationary and at constant temp

LSM6 set to 2000 degrees/s feeding continuously to the FIFO at 208Hz. Solid synchronization on the data coming out of the FIFO. Stationary and at Constant 31 degrees C indicated, in 12500000 samples the average x-gyro reading has drifted from 607 to ...

Calibrating digital magnetometer along only two axis.

I am making a tilt-compensated digital compass with an MMC5983MA magnetometer and a LIS2HH12 accelerometer. I have been calibrating the compass using the min/max method and rotating the compass in free space, which works fairly well.I need to be able...
