Introduction
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.

Heavy duty brackets!
Size: 8 Inch, Color: Gold, Size: 8 Inch, Color: Gold
These brackets are heavy duty and came with the correct hardware. They were easy to install, the two holes were so helpful to know where to mark them. I think because they’re heavy duty you can place a good amount of weight on your shelves. The only thing I wasn’t happy with is that 4/69 of shelves, the paint was chipping but it was the perfect gold color.

Don't hesitate - Great product!
Size: 12 Inch, Color: Black
Superior quality at an unbelievable savings over local retailers. Hardware for hanging included the cheaper plastic lags yet they also included the heavy duty lags, so no tapping in to our supply. Thank you for a great product
