Use Method:


Note : the module should be inserted in the circuit before been power, which avoid producing high level of misoperation;if not, then power again.



1. Adopt IO trigger through supplying at least 10us of high level signal.

3. If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. Test distance =(high level time * sound (340M/S) / 2.



This module is not suitable to connect with electric power, if you need to connect this module with electronic power,then let the GND terminal of this module to be connected first,otherwise, it will affect the normal work of the module
