- Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not.The out pin
- Of this module is used as a switching output when anti-theft module, and without the feet when ranging modules.Note : the module should be inserted in the circuit before been power, which avoid producing high level of misoperation;if not, then power again.
- Adopt IO trigger through supplying at least 10us sequence of high level signal.
- The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal
- 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 velocity (340M/S) / 2
