SRF05

SRF05 Technical Documentation Page 1 of 4 SRF05 - Ultra-Sonic Ranger Technical Specification www.DataSheet4U.com Introduction The SRF05 is an evolutionary step from the SRF04, and has been designed to increase flexibility, increase range, and to reduce costs still further. As such, the SRF05 is fully compatible with the SRF04. 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 SRF04. 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. Mode 1 - SRF04 compatible - Separate Trigger and Echo This mode uses separate trigger and echo pins, and is the simplest mode to use. All code examples for the SRF04 will work for the SRF05 in this mode. To use this mode, just leave the mode pin unconnected - the SRF05 has an internal pull up resistor on this pin. file://D:\shared folders servidor\PDF\Organizada\Sensores\Distancia\SRF05 Technica... 29/05/2008 PDF created with pdfFactory trial version www.pdffactory.com SRF05 Technical Documentation Page 2 of 4 www.DataSheet4U.com Mode 2 - Single pin for both Trigger and Echo This mode uses a single pin for both Trigger and Echo signals, and is designed to save valuable pins ...
