Accelerometer to detect falling off the child in his walker
I want to detect falling off the child walker while the child in it .. I use u-blox C030-U201 IoT Starter Kit and the Accelerometer to measure if the walker fall .. I try to see the relation between x, y, and z but I can't find a specific case for this event. Is the accelerometer sensor can measure these angles for detecting the fall (for right or left) or I need to another sensor??? please help me.

Hi there, I am only beginner but I think you need calculate the pitch, roll and yaw from the acc data. The accelerometer is probably usable but question is how presisly you want to have it and some more.
For start you can read something from these links, maybe it will help.

That could be a little controversial. If a child falls off a 'walker' that would indicate the responsible child minder is not paying attention.
I would suggest that this is not a good project.
What Accelerometer sensor do you have with this kit? I can't see anything on the board page.
This can be used to give you tilt detection in all directions.
