ESP32 | 5-Channel Gray Line Tracking Sensor
01 Introduction This 5-channel line tracking sensor integrates 5 pairs of gray sensors, using TTL communication mode, and supports both digital and analog signal outputs, providing higher anti-interference capability compared to infrared line tracking sensors. 02 Principle The gray sensor consists of a high-brightness white light emitter and a light-sensitive receiver. The emitter emits concentrated … Read more
