I am currently working on a project called double rotary inverted pendulum that requires the use of sensors for accurate measurement with minimal delay and noise interference. I have come across two types of sensors, namely the analogue Hall Effect Potentiometer Angle Encoder Sensor and the digital Rotary Incremental Encoder.
In the context of accuracy, delay, and noise levels, I would greatly appreciate expert insight on which of these two sensors is more suitable for my project. Can someone provide guidance on the pros and cons of each sensor type in terms of accuracy, delay, and noise reduction?
Mechanical movements can be sensed with both analogue and digital sensors. Digital sensors are convenient for data collection. However, analogue sensors require analogue to digital conversion. The accuracy, noise etc are given by the manufacturers as specifications.
The more important aspects regarding use, among these two sensors, are the following:
The Hall-effect sensor is suitable where contactless measurement of angle, for rotational motion, is needed.
Whereas, digital rotary incremental encoder requires contact with the rotating axle.
