ITEM NAME:HW-870 TCRT5000 IR Infrared Reflective Barrier Line Track Sensor Module Product Description Description: HW-870 TCRT5000 IR Infrared Reflective Photoelectric Switch Barrier Line Track Sensor Module Feature: The TCRT5000 infrared emission diode sensor continuously emits infrared light. Infrared rays are emitted when the intensity of the reflection is not reflected or is not large enough. The light activated triode is always off. At this point, the output of the module is high, indicating that the diode is off; When the detected object appears within the test range, the infrared rays are reflected back, and the intensity is large enough. Light activated triode saturation, at this point the output of the module is low, indicating the diode light. Specification: Size: 30*15*10mm/1.18*0.59*0.39" Note: 1. There may be slight size deviations due to manual measurement, different measuring methods and tools. 2. The picture may not reflect the actual color of the item because of different photographing light, angle and display monitor. Included: 1 X Barrier Line Track Sensor Module.Find many great new & used options and get the best deals for HW-870 TCRT5000 IR Infrared Reflective Barrier Line Track Sensor Module at the best online prices at !
