Is a flex sensor analog or digital?

A flex sensor that is placed on a hinge or flexing joint or similar (like an elbow, finger, or robotic arm actuator) outputs an analog signal and usually required conversion through a device like and Arduino through its analog pin(s).
Analog to digital conversion is required so that the changing voltage values due to bend, will be in a format (digital) which the software can use.
There are several standard and well tested ways to interface Spectra Symbol flex sensors with many different applications. Rest assured we are ready to help answer any questions you have about your specific flex/bend sensing application!
