| Sensor angle | Not more than 15 degrees |
| Detection distance | 2cm-450cm |
| High precision | Up to 0.3cm |
| Input trigger signal | 10us TTL impulse |
| Echo signal | output TTL PWL signal |
| Mode of connection | 1.VCC 2.trig(T) 3.echo(R) 4.GND |
Use method:
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.
Module Working Principle:
1.Adopt IO trigger through supplying at least 10us sequence of high
level signal.
2.The module automatically send eight 40khz square wave and
automatically detect whether receive the returning pulse 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 velocity (340M/S) / 2.
Note : 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
