• SRF05 - Low cost Ultrasonic Ranger

This sensor from Devantech uses echo (ultrasound) to measure the distance between sensor and detected object. 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 time to execute their pulse in commands.
