Question on SN-IMU5D-LC

Hello cytron,

For the part SN-IMU5D-LC, is it a gyro plus an accelerometer? Or..rather on the gyro part, it actually measure the 'rate' of the turn instead of static angle. I am looking for a part that can measure static angle relative to flat ground.

Re: Question on SN-IMU5D-LC

Yes, the IMU is actually the combination of gyro and accelerometer. To measure the tilt angle relative to ground in static condition (the sensor is static and not moving), you can use only the accelerometer itself. If you want to measure the angle in dynamic condition (the sensor is moving, example: quad copter, balancing robot) then you need to combine the reading from both the gyro and accelerometer with complementary filter or even Kalman Filter.

tumpang tanya,
atan2 function memang ada dlam compiler hitec ke?
include math.h je kan?
no need buat function dia?

Re: Question on SN-IMU5D-LC

i have use imu and complementary filter and interrupt 10ms,
and the result look good at LCD, but motor not fast response based on error.
is it have any idea?
