Module consisting of ultrasonic transmitter, receiver and\ncontrol circuit. Basic working principle: 1. Use IO mouth TRIG trigger\ndistance, at least 10 high level US signals; 2. The module automatically sends\neight 40KHz square waves and automatically detects whether a signal is\nreturned. 3. I returned the signal, through the IO mouth, ECHO output a high\nlevel, the duration of the high level is the time of the ultrasonic wave from\nstart to return. 4. Distance = test (high level time  speed of sound (340\nm\/s)) \/ 2; Operating voltage: DC 5V Operating current: less than 2mA Working\nfrequency: 40Hz maximum range: 450CM Minimum range: 2 CM Measuring point: 15\ndegrees Input trigger signal: 10US TTL pulse Echo signal output: Output the\nTTL level signal, proportional to the range. Document link:\n Note 1: The TRIP pin is an\ninternal pull-up resistor of 10K. Use the IO port of the microcontroller to\npull the TRIP pin low, and then give a pulse signal of more than 10us. The OUT\npin is the switching output pin when this module is used as an anti-theft\nmodule. This pin is not used in the ranging module. Note 2: The module should\nbe plugged into the circuit board first and then powered on to avoid high-\nlevel malfunction. If it occurs, it can be solved by repowering it.
