BMI323 IMU Sensor for Excavator Angle Measurement

[Sololurd]

Hello

I want to use one of your IMU sensors (BM1323) for my excavator project. I want to confirm the application. Is it right to use this for angle measurement in the excavator, or do you have other recommendations? I would appreciate your swift response.

Hi,

Thanks for your inquiry.

For excavator application BMI088 is better choice than BMI323, because BMI088 gyro is close-loop with better zero-rate bias, TCO and bias instability and BMI088 accel has better vibration robustness.

Thanks.

Hello, I have a few more questions. I just received the delivery of BMI088. I want to ask about the possible connection of the IMU to an Arduino Pro Mini Microcontroller, as this project aims to collect angle measurements using the Raspberry Pi remotely due to the complexity of the excavator. Thanks for your help, and I look forward to your swift response.

Hi,

You can use Arduino Pro Mini 3.3V board to connect to BMI088. The I2C connection is as shown below.

You can connect Arduino Pro Mini 3.3V to both BMI088 VDD and VDDIO; GND to BMI088 GND; SCL to BMI088 pin-8 and SDA to BMI088 pin-9.

If you want to use BMI088 API examples, you can refer to Github at https://github.com/boschsensortec/BMI08x_SensorAPI for more information.

Thanks.
