The RGB components of the object's colour are distinguished based on the principle that objects of different colours have different reflectivity of RGB light
Based on pyroelectric infrared sensors
the sensor output value will increase
At the same time
high level works
Line Follower Sensor The RGB components of theIt can be used for tracking line detection. When black is detected, it outputs a high level, and when white is detected, it outputs a low level. Based on the infrared reflection principle, the infrared emitting diode continuously emits infrared rays, and the infrared photoelectric transistor receives the reflected infrared light. Since white has strong infrared reflection and black has weak infrared reflection, black and white lines can be detected.
