Ultrasonic Distance Sensor Module - Code: 70316 - SPECIAL!

*****This product is reduced to clear*********

An economical ultrasonic range finder module ideal for use in distance measurement projects and obstacle avoidence robots. Ideal for Arduino and other development systems.

Use with our range finder LED display module Code: 70293 - See Pictures

Module main technical parameters:

1.Working Voltage : 5V(DC)
2.2mA.Static current: Less than
3.Output signal: 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

Connections:
1.VCC
2.trig(T)
3.echo(R)
4.GND
5.GND

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.Provide I10us pulse TTL signal to "trig" input.
2.The module automatically sends eight 40khz square wave and automatically detects whether a reflected pulse is received.
3.If there is signals returning, an output on the "ehco" output of a high level. The on period determins the distance
Test distance = (high level time * sound velocity (340M/S) / 2.
