1、This module provides a versatile infrared detection system solutions for automation machinery devices. 2、It uses TCRT5000 infrared reflection sensor whose infrared emitting diodes are constantly emitting infrared rays. 3、When the infrared ray emitted is not reflected back or intensity is not high enough, the infrared receiving tube is in the off state and module outputs low level,while indicating diode is off. 4、When object is in detecting range, infrared ray will be reflected back with high intensity, the module outputs high level and indicating diode is on. 5、Widely used for electricity meter pulse data sampling, fax machine paper detection, obstacle detection, black and white line detection. <strong><span style="font-family:Arial;font-size:16px;">Features:</span></strong> <ul> <li> <span style="font-family:Arial;font-size:16px;">This module provides a versatile infrared detection system solutions for automation machinery devices.&nbsp;</span> </li> <li> <span style="font-family:Arial;font-size:16px;">It uses TCRT5000 infrared reflection sensor whose infrared emitting diodes are constantly emitting infrared rays.</span> </li> <li> <span style="font-family:Arial;font-size:16px;">When the infrared ray emitted is not reflected back or intensity is not high enough, the infrared receiving tube is in the off state and module outputs low level,while indicating diode is off.</span> </li> <li> <span style="font-family:Arial;font-size:16px;">When object is in detecting range, infrared ray will be reflected back with high intensity, the module outputs high level and indicating diode is on.</span> </li> <li> <span style="font-family:Arial;font-size:16px;">Widely used for electricity meter pulse data sampling, fax machine paper detection, obstacle detection, black and white line detection.</span> </li> </ul> <strong><span style="font-family:Arial;font-size:16px;">Specification:</span></strong> <span style="font-family:Arial;font-size:16px;">Detection Reflecting Range: 1mm~25mm</span> <span style="font-family:Arial;font-size:16px;">Working Voltage: 5V</span> <span style="font-family:Arial;font-size:16px;">Output Form: Digital signal (0 and 1)</span> <span style="font-family:Arial;font-size:16px;">PCB Size: 3.5*1cm / 1.4*0.4in</span> <span style="font-family:Arial;font-size:16px;">Weight: 8g / 0.3oz (approx.</span><span style="font-family:Arial;font-size:16px;">)</span> <span style="font-family:Arial;font-size:16px;">Wiring Method: </span> <span style="font-family:Arial;font-size:16px;">VCC: Power supply positive (5V)</span> <span style="font-family:Arial;font-size:16px;">GDN: Power supply negative</span> <span style="font-family:Arial;font-size:16px;">OUT: High/low level on-off signal (digital signal 0 and 1</span><span style="font-family:Arial;font-size:16px;">)</span> <strong><span style="font-family:Arial;font-size:16px;">Package list:</span></strong> &nbsp;<span style="font-family:Arial;font-size:16px;">3 *&nbsp;Infrared Tracking Sensor Modules </span>
