Devantech SRF05 Low-Power Ultrasonic Range Finder

$29.00

Click for larger image
The SRF05 is an evolutionary step from the SRF04, and has been designed to increase flexibility, increase range, and to reduce power, all while maintaining the same dimensions and pinout as the SRF04. 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.

This product is made by Devantech. More information, applications, and code samples may be found on their web site.

An optional SRF05 Mounting Bracket is also available.
