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.
NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.
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.
