Sensor Accuracy and error information

Is there any info available on sensor accuracy and error limits?

 

I.e. reading the Gyro Z axis on my stationary PB does not give a zero result. It reads at about 4-5mrad/s.

 

Specifically for the gyro, but in general for all sensors:

 

What is the accuracy? i.e. what is the smallest angular rate of change that the gyro can detect?

What is the error? i.e. X rad/s +/- y mrad/s ?

Re: Sensor Accuracy and error information

Generally this info isn't available as the sensors can often change.  If an application is coded for playbook using noise/accuracy/error info specific to playbook sensors, the application might not perform well on another product.

 

Having said that, take a look at sensor_info(sensor_type_t type, sensor_info_t **info), it contains some of the info you are interested in.
