The optical (reflective) module sensor with LM393 comparator, which detects obstacles with high accuracy. The ideal detector for obstacle detection for the installation of intelligent 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 an object using infrared reflection on the object. The transmitter is an infrared LED and the receiver is a phototransistor. The sensor allows the detection of an object at a distance of up to 3.5 cm from the white paper and 1 cm from the person's finger.
