Joy-it IR sensor 1 pc(s) Compatible with (development kits): Arduino, ASUS Tinker Board, micro:bit, Raspber

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) This text is machine translated.
