This sensor sends and receives infrared. This allows the sensor to detect whether it has a reflective surface (the sensor receives its own signal) or an absorbing surface (the sensor does not receive a signal) in front of it. The sensitivity of the sensor can be adjusted using a potentiometer. Robots can use three of these sensors to perform an automated line tracker function. Working voltage: 3.3 V-5 V Power consumption: 3V= 7mA, 5V= 13mA IO Interface: 3 interfaces (G/V +/S) Output signal: TTL level (low is an obstacle, no obstacle high) https://elecena.pl/product/28015651/joy-it-infrared-line-tracker 2025-03-12 https://elecena.pl/product/28015651/joy-it-infrared-line-tracker 2025-05-22 https://elecena.pl/product/28015651/joy-it-infrared-line-tracker 2025-07-18 https://elecena.pl/product/28015651/joy-it-infrared-line-tracker 2025-09-17
