In the Week 2 force sensor lab, why is it important to construct an appropriate conditioning circuit?

we are using a microcontroller, so we don't have enough memory to do it with an embedded system.

to maximise the dynamic range of the whole system

to account for how the foam wears down with repeated use

to avoid having to calibrate the sensor every time we use it

What might cause any errors observed? Check all that apply.

The sensor is biased

No errors observed

Dynamic errors

Invaild theory

Reader error

Transient equipment failures

Does the sample contain outliers?

Need more or different data

Yes

Is the sensor accurate?

Need more or different data

Yes

Is the sensor precise?

Need more or different data

Yes
