Basic working principle
(1)Use 10-port TRIG trigger ranging, give at least 10us high level signal
(2) The module automatically sends eight 40khz square waves to automatically detect whether there is a signal return; (3) If there is a signal return, a high level signal is output through port 10 ECH0.
(3)If there is a signal return, output a high level through port 10 ECH0, the duration of the high level is the time that the ultrasonic wave is returned from the transmission. Test distance = (high level time * speed of sound (340M/S))/2.
This module is simple to use, a control port sends a high level of more than 10US, you can wait for a high level output in the receiving port. An output can open the timer, when the port becomes low, you can read the timer value, this time for the time of the distance measurement, so that the distance can be calculated. Such a continuous cycle of measurement, that is, you can reach the value of the mobile measurement. 3, the object is close, the presence of detection
