Connection mode, VCC, trig ( control side), echo ( receiver ), GND wire
This product use: a control orifice with a 10US above high level, can be in the receiving port to wait for high level output. The output of the timer can be opened, when the orifice is low we can read the timer value, this time for the ranging time,We can calculate the distance. So continuous cycle test, can achieve your mobile measurement value.
Module working principle:
(1) using IO trigger location, to at least10us high level signal;
(2) module to automatically send8 40KHz square wave, to automatically detect whether a signal return;
(3) a return signal, through the IO outputs a high level, high level for a time is Ultrasonic wave from the transmitter to the return time. Testing distance = ( high level time * speed of sound (340M/S ) ) /
