HC-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 the item. The HC-89 sensor, as well as possibly related circuitry for communicating with a microcontroller or other device, is probably certainly present in the module you indicated. This is Speed Measuring Sensor Module For Arduino . An infrared emitter on one side and a receiver on the other side is used to detect the speed or RPM. There is an encoder wheel used to measure RPM that is placed between the sensor. The DO output interface can be directly connected to a micro-controller IO port if there is a block detection sensor, such as the speed of the motor encoder can detect. Pin Details: VCC: The positive 3.3-5 v power supply. GND: Connect power negative. DO: TTL switch signal output. AO: This is an analog output.
