• 6. Artificial intelligence and research

Working Principle:

• 1. Use the TRIG trigger position of the IO port to reach a high level signal of at least 10us

• 2. The module automatically sends 8 channels of 40KHz square wave, and automatically detects whether there is a signal return

• 3. Signal return, output high level through IO port ECHO, and the duration of high level is the ultrasonic wave from transmitting to returning. Test distance = (high level time * speed of sound (340M/S))/2

• 4. This module adopts a simple method. A high-level control port above 10US can wait for a high-level output at the receiving port. An output can drive a timer. When the port is low, the timer value can be read. This time is the positioning time, and the distance can be calculated. By repeating the test in this way, you can measure the value of your phone
