Devantech SRF02 Sonar Rangefinder

This Devantech ultrasonic sonar ranging module has I2C and Serial interfaces with a range of 16 cm to 6 m (about 6 inches to 19 feet). Special commands include the ability to send an ultrasonic burst without a reception cycle, plus the ability to perform a reception cycle without the preceding burst -- a popularly requested sonar feature introduced on this sonar first. A single transducer for transmission and reception means the SRF02 has a minimum range that’s higher than our dual-transducer receiver. Switch from measuring in centimeters or inches for ease of reading and data import. This rangefinder has a small footprint for easy integration that leaves space for other components.
