IMU and other sensors

These pages are for learning a little more about i2c interfaced sensors.

Going from raw sensordata to engineering units like (acceleration m/s2, altitude m, pressure Bar or N/m2 and more.

We use an Arduino UNO and a gy-91 sensor board and an Openlog
logger for storing data on a micro sd card. In short AAUIMUKIT

All powered by a 9V battery, a powerbank (by USB) or you PC by USB

Below is an image of our small controller device:

 

The sensor board carry (in bold)

  • Pressure an temperature sensor

    • bmp085 bmp180 bmp280 bmp285

  • IMUs

    • MPU6000 MPU6050 MPU6250 MPU9250

  • Mag field sensors

    • HMC5883 - not used here
