detect the pitch angle of a moving car

Using Arduino Sensors
1

Hi,
I am working on a new project were I need to detect the pitch angle of a moving car so knowing that i what to make thing as simple as possible waht gyroscope or sensor should i use ?

You are looking to make an inclinometer -google and you tube will have the info you need.

Really a simple sensor (like those used for quadcopters and the like) with a small oled or lcd screen should do you.

Take a look at this for starters....

Good luck!

Its a full IMU you need - an inclinometer is only for stationary use.

By pitch angle you mean the actual pitch w.r.t. gravity vector? Or the apparent pitch due to acceleration
as well.

thanks for your answer ,

what i need is just the angle relative to horizontal ( the angular position )

does it exist a sensor that mesure directly the angular position , because for what i see the gyroscope mesure the angular velocity

A "direct" measurement would be something like a protractor. Like maybe you measured the height of the bumper at the front and back and then subtracted them.

A pair of ultrasonic or laser sensors can be mounted on the car to measure the "height" of the road. But that may not be the measurement you want if you're driving up a hill.

The IMU type sensor which combines acceleration and gyroscope into the one unit is likely to be the solution you're looking for.
