Taidacent Car Robot 4 Way Tracking Module Line Patrol Optical Tracking Sensor Infrared Tracking Black and White Line Recognition -Module with Cable-

Parameter Working voltage: 3.3V~5V Working current: 10mA~50mA Working temperature: -10?~+50? Detection distance: 1mm~10cm adjustable Installation aperture: M3 copper column/screw Product size: 70*29mm Output interface: 6pin interface 1234 is 4 signal output terminals, + is positive power supply,-is negative power supply Output signal: TTL level (can be directly connected to the I/O port of the single-chip microcomputer) Inside line recognition The two probes in the middle of the four-way tracking probe can identify black lines above 16mm in width. After long-term testing, we concluded: 1. The width of electrical tape is generally 16-20mm 2. The width of the black line of a race or map track is generally greater than 20mm, so we will recognize the inside line Do not set the golden ratio above 16mm. Outside line warning The two probes outside the four-way tracking probe can detect the black line at a large angle in advance when the smart car is following a black line curve, so that the car can achieve difficult tracking functions such as 90° turning. Installation method Use M3 copper pillars and screws to install at the bottom of the smart car, keeping 0.8cm away from the ground. For conventional chassis, 23mm length is recommended for M3 copper pillars Flat-wire connection (recommended, use this method to connect this module with the BST-4WD smart car expansion board) Dupont line connection (can be used separately with the development board IO port pin header/seat connection)
