    Operating temperature in ambient environment - BMI088

    Hi all,

    The datasheet states that the operating temperature range is -40°C to 85°C but I would like to know how hot it is when working in the environment temperature. I tried mine and it's around 55°C which is hotter than I thought. Is it normal?

     

    Thanks!

    Hi,

    Thanks for your inquiry.

    BMI088 works from -40C to +85C. It consumes about 5.15mA when both accel and gyro are working in normal mode. At 3V power supply BMI088 only consumes 15.45mW power. So it doesn't generate heat by itself.

    The temperature sensor inside BMI088 can measure the environment temperature if you want to do temperature compensation on accel and gyro data.

    Thanks.

    Thanks for the reply. Do you mean that the operating temperature should be very close to the ambient temperature? If the answer is yes, I could expect that the heat is coming from other sources.

    Hi,

    Yes, BMI088 has built-in temperature sensor. The temperature measurement from BMI088 temperature sensor is very close to the environment temperature that may come from the air or other components on the same PCB.

    Thanks.
