The obstacle sensor based on the TCRT5000 uses an infrared diode and a photoreceiver to detect objects in front of it - the emitted light reflects directly back to the sensor. This technology enables precise detection of obstacles and is particularly effective for use in small robots, especially for line tracking purposes. https://elecena.pl/product/25847775/333012-developer-boards-obstacle-sensor-ctrt5000 2024-05-11 https://elecena.pl/product/25847775/333012-developer-boards-obstacle-sensor-ctrt5000 2025-09-27
