Seeed Studio Studio Grove Line Finder v1.1 Line Tracking Sensor - TTL Digital Output
The Seeed Studio Studio Grove Line Finder v1.1 is a TTL digital output sensor module designed for line-following robotics and automated guidance systems. It integrates an IR LED and phototransistor pair with an LMV358 comparator, providing a simple HIGH/LOW signal for detecting contrasting surfaces and is compatible with 5V microcontrollers like Arduino and Raspberry Pi via the Grove connector.
Features
- TTL Digital Output (HIGH/LOW) for direct microcontroller interfacing.
- Adjustable detection range via onboard potentiometer for sensitivity tuning.
- Integrated IR emitting LED (RS-06WD) and sensitive phototransistor pair.
- 5V DC operating voltage with Grove 4-pin buckled connector for plug-and-play use.
- Compact form factor (25mm x 20mm) for space-constrained robotic applications.

The Grove Line Finder v1.1 operates on an infrared reflectance sensing principle. The onboard IR LED emits light, which is reflected off the surface below and detected by the adjacent phototransistor. The LMV358 comparator processes this analog signal, outputting a clean digital TTL signal—typically HIGH when detecting a white (reflective) surface and LOW for a black (absorptive) line.
This sensor is engineered for reliability in automated guidance tasks, offering a stable digital interface that eliminates the need for external signal conditioning. Its robust construction and simple wiring via the Grove ecosystem make it suitable for educational robotics, industrial line-following carts, and automated material handling systems requiring basic optical contrast detection.
