Principle of infrared intelligent crutch

The computer instructs the sensor and transmitter to emit infrared rays, which are then received by the receiver. The principle of infrared intelligent crutch is that the computer directs the sensor and transmitter to emit infrared rays, and then the infrared rays are received by the receiver. The receiver transmits the data to the computer, and the computer draws a graph, and then combines the data measured by the hygrometer for rapid analysis, and then converts the analysis result into voice, and informs the user of the road ahead, what obstacles are around and how far the obstacles are from the user through Bluetooth.
