Vertical movement sensor

[lukebarber]

Hi,

I posted this question in the forum yesterday. But for some reason I cannot find it again. I'm sorry if this is a double post.

I am wondering if anyone knows a sensor that only detects a vertical up and down movement?

I came across a sensor that could work for my application but it's very expensive.

I thought of using a single axis accelerometer but the sensor will be rotating in my application. I tried using an altimeter/pressure sensor; but it was too sensitive to interference from local airflow near the sensor.

The location is not fixed. I may have to get a 3DOF or 9DOF IMU and read out only one of the axes. I'm not sure if it would work either.

Any suggestions would be greatly appreciated.
