Grayscale Sensor

Product introduction

The working principle of tcrt5000 reflective photoelectric switch is the same as that of general infrared sensors. Tcrt5000 has an infrared transmitting tube and an infrared receiving tube. When the infrared signal of the transmitting tube is received by the receiving tube through reflection, the resistance of the receiving tube will change, which is generally reflected in the form of voltage change on the electric circuit, and the processed output result will be obtained after ADC conversion or LM324 circuit shaping, The change of resistance depends on the intensity of the infrared signal received by the receiving tube. It often shows the color of the reflecting surface and the distance of the receiving tube of the reflecting surface.

The tracking (digital) sensor helps the robot track the white line or black line with a stable digital output signal (it can detect the black line in the white background or the white line in the black background). The product has high sensitivity and strong anti-interference ability. Ordinary lighting lamps basically have no influence on it. It can be spliced with Arduino on the trolley. Through the cooperation of multi-channel sensors, the effect of fast line inspection can be achieved. It can be said to be a good product for robot research competition and interests.
