The optical module sensor (reflective) with comparator LM393, which detects obstacles with high precision.
The ideal obstacle detection detector for the installation of smart robots.
TCRT5000 - reflective optical sensor that has a compact construction where the light emitter and receiver are placed in the same direction to detect the presence of a object using infrared reflection on the object.
The working wavelength is 950nm.
The transmitter is infrared LED and the phototransistor receiver.
By using LM393 comparator the module has a binary output (D0) that is at level 1 (object is detected).
The sensor allows the detection of an object at a distance of up to 12 mm.
