This line detection module uses the TCRT5000 (emitter and detector combo) to detect the reflection of a material at a distance of 0 to 3 cm. This module provides both analog and digital output for easy use. Both a supply voltage of 3.3 V and 5 V are suitable for this module. https://elecena.pl/product/27738541/opencircuit-tcrt5000-infrared-line-detection-module 2025-01-22 https://elecena.pl/product/27738541/opencircuit-tcrt5000-infrared-line-detection-module 2025-03-22 https://elecena.pl/product/27738541/opencircuit-tcrt5000-infrared-line-detection-module 2025-06-17 https://elecena.pl/product/27738541/opencircuit-tcrt5000-infrared-line-detection-module 2025-06-18 https://elecena.pl/product/27738541/opencircuit-tcrt5000-infrared-line-detection-module 2026-02-23 https://elecena.pl/product/27738541/opencircuit-tcrt5000-infrared-line-detection-module 2026-02-25 https://elecena.pl/product/27738541/opencircuit-tcrt5000-infrared-line-detection-module 2026-04-08
