ACEBOTT Infrared Obstacle Avoidance Sensor

Description

The infrared obstacle avoidance sensor transmits infrared light through a transmitter, and detects the change in the amount of light reflected by the detection object or blocked by the receiver to obtain an output signal. The working principle of infrared obstacle avoidance sensor is based on the photoelectric effect, which converts photon energy into electron energy. Infrared obstacle avoidance sensor mainly includes light source, receiver, signal processing circuit and other parts. Among them, the light source is mainly used to irradiate the object to be detected with a certain light intensity, and the receiver receives the light signal reflected, transmitted, scattered or emitted from the object to be detected through the photosensitive element, and converts it into an electrical signal. Finally, the signal processing circuit amplifies, filters, compares and counts the electrical signal to realize the detection and control of the object.
