Range detection sensor
The ultrasonic sensor is responsible for transmitting ultrasonic ultrasonic waves and is responsible for receiving ultrasonic waves. The speed of sound waves propagating in the air is 340m / s. According to the time difference between transmission and reception, the distance between the machine and the obstacle can be calculated, so as to avoid collision and transparent objects can be correctly sensed.
