SparkFun RedBot Sensor - Line Follower
The SparkFun RedBot Line Follower sensor is an infrared reflective sensor designed for robotics platforms like the RedBot, Arduino, and Raspberry Pi. It provides digital output for detecting surface contrast transitions, enabling line-following and basic proximity sensing applications.
Features
- Infrared reflective sensing principle for non-contact detection.
- 5VDC operating voltage compatible with common microcontroller logic levels.
- Compact PCB design with integrated IR LED and phototransistor receiver.
- 3-pin header (VCC, GND, OUT) for direct connection to development boards.
- Includes mounting hole for secure installation on robotic chassis.

The SparkFun RedBot Line Follower sensor operates on the principle of infrared reflectance. An onboard infrared LED emits light, which is then reflected off a surface and detected by a paired phototransistor. The amount of reflected IR light varies with surface color and proximity, allowing the sensor to distinguish between light and dark areas or detect close-range objects.
This sensor outputs a digital signal, making it straightforward to interface with microcontrollers like the RedBot Mainboard, Arduino, or ESP32. Its fast response time and high sensitivity make it suitable for real-time robotic control applications such as line-following competitions, edge detection, and simple obstacle avoidance.
