TCRT5000 Reflective Optical Sensor IR Switchs for Arduino (2 PCS)
Compact construction£¬ sense the presence of an object by using the reflective IR beam from the object. Consists of a phototransistor. Snap-in construction for PCB mounting. Plastic polycarbonate housing construction which prevents crosstalk. Position sensor for shaft encoder. Detection of reflective materials such as paper£¬ IBM cards£¬ magnetic tapes£¬ etc. Limit switch foe mechanical motions in VCR. General purpose - wherever the space is limited.
