Consumer Shop with prices incl. EUR VAT Price excl. Lowest cost ultrasonic ranger with both I2C and Serial interfaces. New AutoTune algorithms intelligently back the minimum range right up to the transducer ringdown for the very best performance possible, automatically, in the background, and with no calibration cycles necessary. Additional new commands allow for separate burst and ranging control.

It features both I2C and a Serial interfaces. The serial interface is a standard TTL level UART format at baud,1 start, 2 stop and no parity bits, and may be connected directly to the serial ports on any microcontroller. New commands in the SRF02 include the ability to send an ultrasonic burst on its own without a reception cycle, and the ability to perform a reception cycle without the preceding burst.
This has been as requested feature on our sonar's and the SRF02 is the first to see its implementation. Because the SRF02 uses a single transducer for both transmission and reception, the minimum range is higher than our other dual transducer rangers.
The minimum measurement range varies from around cm 7 inches on a warm day down to around cm 6 inches on a cool day. Like all our rangefinders, the SRF02 can measure in uS, cm or inches. It has an internal pull-up resistor. When in IIC mode,the "Mode" pin should be left unconnected. Of course,if you don't have a Leonardo board, you can also use the Arduino UNO by the software serial.
Just change "Serial1" into "mySerial" and add these sentence:. SRF02 Ultrasonic sensor user manual.
