Product Introduction

Product Description:

Module main technical parameters:

1.Working Voltage : 5V(DC)

2.Static current: Less than 2mA.

3.Output signal: Electric frequency signal， high level 5V， low level 0V.

4.Sensor angle: Not more than 15 degrees.

5.Detection distance: 2cm-450cm.

6.High precision: Up to 0.3cm

7.Input trigger signal: 10us TTL impulse

8.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.
