Ultrasonic Ranging Module HY-SRF05 for Arduino and Robot ***LOCAL STOCK***

Ultrasonic Ranging Module HY-SRF05 for Arduino and Robot

An ultrasonic range finder module ideal for use in distance measurement projects and obstacle avoidence robots. Ideal for Arduino and other development systems. More accurate than the HC-SR04.

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 0.2cm
7.Input trigger signal: 10us TTL impulse
8.Echo signal : output TTL PWL signal

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

Note : the module should be inserted in the circuit before being power, which avoids 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.
