HC-89 Interrupt Sensor Obstacle sensor The Voice Recognition Module canHC 89 Interrupt Sensor The HC 89 Interrupt Sensor is a sensor module that measures the rotational speed of an object. A Hall Effect sensor, which detects the existence of a magnetic field, is commonly used to measure the speed of an item. The rotational speed of a motor, wheel, or other spinning object is measured by this sensor. The output of the sensor is typically in the form of a square wave, with the frequency of the wave related to the speed of
