Description

This is the low-cost successor to the extremely popular SRF04 detector. The design for manufacturing has allowed the price to come down with better features including an LED status indicator that blinks when the sonar fires as well as a new single-wire mode of operation. In most all other respects, this is a drop-in equivalent of the SRF04. The range has also increased to 4 meters.

For further range see the SRF08. The SRF05 is interfaced using the one output line to ping the sensor and an input line to read the echo. The sensor can also be run using a single IO line.
