Hi,
I would like to ask a question on Tilt angle sensing.
If there is an application which requires the device to be on the upright position, and should generate an error whenever there is an oblique angle between device’s top direction and the upright direction, what sensor should be used to detect it?
I read some articles on Wikipedia and there seems to exist a number of solutions, and several types of sensor are capable of doing that. Accelerometer, like those on iPhone, could obviously do it. Among accelerometers, there are 1, 2 and 3-axis type. Besides accelerometer, there also appears to be some tilt sensor whose sole purpose is to measure tilt angle.
My only need is to measure tilt angle from upright direction, which a relatively low (I presume) accuracy: 2° is enough. The smaller the better, and the cheaper the better. Which type should I choose?
Does anyone have experience on this? Could anyone recommend some solutions?
