HC-89 Interrupt Sensor R385 DC PUMP Breadboard Friendly: Pre-soldered header pins```html HC 89 Interrupt Sensor The HC 89 Interrupt Sensor is a compact, slotted optical switch module designed for precise object detection, position sensing, and counting applications. Featuring an infrared LED and phototransistor pair housed in a U shaped gap, this sensor reliably detects when an object passes through or interrupts the optical beam making it essential for encoder wheels, motor speed measurement, end stop detection, and automated
