Description
Specifications

The SRF05 is an evolutionary step from the SR04, and has been designed to increase flexibility, increase range, and to reduce costs still further. As such, the SRF05 is fully compatible with the SR04. Range is increased from 3 meters to 4 meters. A new operating mode (tying the mode pin to ground) allows the SRF05 to use a single pin for both trigger and echo, thereby saving valuable pins on your controller. When the mode pin is left unconnected, the SRF05 operates with separate trigger and echo pins, like the SR04. The SRF05 includes a small delay before the echo pulse to give slower controllers such as the Basic Stamp and Picaxe time to execute their pulse in commands.

Provides precise, non-contact distance measurements to 4 m range.
Ultrasonic measurements work in any lighting condition, making this a good choice to supplement infrared object detectors.
5-pin header (2.54 mm spacing) makes it easy to connect to a development board, directly or with an extension cable, no soldering required.
Narrow acceptance angle.

Send a pulse signal to I/O TRIG which is at least 10us long, this will activate the module to start detecting
The ultrasonic module will automatically send eight 40khz square waves, and will automatically detect when there is a reflect signal

When there is an reflect signal back, the ECHO I/O will output a high level, the duration of the high-level signal is the time from untral sonic launch to return. As a result, the Measured distance = (T(Time of High Level output ) * (340M / S)) / 2The reason for the division by two is that since this is a echo it has traveled both to and from the object. Note the speed of sound is dependent of the temperature so keep that in mind if you need accuracy
