This sensor transmits and receives infrared. It can detect whether it has a reflective surface (the sensor receives its own signal) or an absorbent surface (the sensor does not receive a signal) in front of it. The sensitivity of the sensor can be adjusted using a potentiometer. Robots, for example, can use three of these sensors to perform an automated line tracker function. Technical specifications - Function: Detects a line using infrared (0/1 signal output) / With three of these sensors, robots can automatically follow a line - Detection range: 1 - 25 mm - Supply voltage: 3 - 5 V - Power consumption: 3 V approx. 7 mA / 5 V approx. 13 mA - Operating temperature: 0 °C to 50 °C - Dimensions: 42 x 11 x 8 mm https://elecena.pl/product/29534929/sen-ky033lt-developer-boards-line-tracker 2025-11-25 https://elecena.pl/product/29534929/sen-ky033lt-developer-boards-line-tracker 2026-02-20
