Tilt angle sensor

Central SUPPORT

We are looking for a sensor that can identify tilt angle with respect to gravity. I have been looking around at 3-axis accelerometers but cannot be sure if these will work as a tilt angle sensor. Please advise.

Yes, you can use many of our LIS2 and LIS3 devices for this purpose, see more info here https://www.st.com/content/st_com/en/products/mems-and-sensors/accelerometers.html  

There you will find an application note AN4509 (also attached here) describing “tilt sensing theory and the methods of determining tilt angle measurement of a low-g 3-axis accelerometer�?. This will certainly help.

With a 3-axis accelerometer and a bit of vector calculus, no problem.
