TCRT5000 sensor infrared emission diodes continue to emit infrared, when the emitted infrared rays are not reflected back or reflected back but the intensity is not big enough, the infrared receiver tube has been in the off state, then the module output is low, indicating The diode is in the extinguished state; when the object is detected within the detection range, the infrared rays are reflected back and the intensity is large enough, the infrared receiver is saturated, and the output of the module is high, indicating that the diode is lit. 3, OUT: high / low switching signal (digital signals 0 and 1) DISCOUNTS IN CASE OF MULTIPLE PURCHASES, SIGNIFICANT SAVINGS !!! PRIORITY MAIL (NOT TRACEABLE, DELIVERY IN 2 - 3 WORKING DAYS) REGISTERED MAIL (SAFE AND TRACEABLE, DELIVERY IN 4 - 5 WORKING.
