Choosing the Right Input Sensor
With so many types of input sensors available, you need to narrow down
your selection to what will give you the feedback required. As with
human "input sensors," each type has a dedicated function. You need to
match the sensor with the object being sensed and what that feedback
Another consideration is the action taken when the sensor notices a change of state. In our human example, a sudden bright light sends a signal to the brain, causing us to shield our eyes.
