The Digital Line Tracking Sensor is designed for Arduino applications and is compliant with RoHS standards. It operates within a voltage range of 3.3V to 5V and features a digital output that provides TTL signals, indicating black as LOW output and white as HIGH output. The sensor has an operating current of 20mA at 5V and functions effectively within a temperature range of 0¬8C to +50¬8C. This sensor is particularly useful for line-following robots, allowing them to distinguish between black and white surfaces quickly and accurately. Its improved sensitivity is attributed to a high-quality opto interrupt, making it suitable for various mobile platforms. The compact size of 28x10mm facilitates easy integration into robotic designs. Additionally, the sensor can be utilized for detecting areas based on floor color and can assist in obstacle detection, such as stairs, by identifying low-reflection surfaces.
