This module is easy to use. If a control port sends a high level above 10US, you can wait for the high level output at the receiving port. The timer can be started as soon as there is an output. When the port becomes low, the timer value can be read. At this time, it is the time of this distance measurement, and the distance can be calculated. Such continuous periodic measurement can be Reach the value of your mobile measurement.
