How does ultrasonic obstacle avoidance work?

    1.
    Transmitter (trigger pin) sending signal: high-frequency sound.
    2.
    When a signal finds an object, it is reflected.
    3.
    Receiver (echo pin) : Receives the signal reflected back from it
The HC-SR04 ultrasonic sensor detects how far ahead an obstacle has appeared.If there is an obstacle in your specified detection range, the car can make corresponding actions.For example, forward, back, turn left or turn right.

How does Four channel tracking module work?

The sensor belongs to infrared reflection detection, so the reflectivity and shape of the target is the key to the detection range. Among them, the black detection distance is the smallest and the white detection distance is the largest. Small area object distance is small, large area distance is big. Infrared detection method, that is, the use of infrared light in different colors of the object surface has different reflection intensity characteristics, in the process of the car constantly emitting infrared light to the ground, when the infrared light encounter white paper floor diffuse reflection, reflected light is installed in the car received by the receiving tube;If a black line is encountered, the infrared light is
Absorbed and the receiver tube on the car does not receive the infrared light. MCU on whether to receive the reflected infrared light as the basis to determine the location of the black line and car travel route.
