OVERVIEW

The SRF01 is a single transducer ultrasonic rangefinder with an extremely small footprint. Connection is to a single pin serial interface. The serial interface is a standard TTL level UART format of 1 start, 1 stop and no parity bits. Baud rate at power-up is always 9600, there is a command to change this to 19200 or 38400 baud if preferred. Up to 16 SRF01's can be connected together on a single bus. Like all our rangefinders, the SRF01 can measure in cm or inches.

3-pin JST connector, three wires and grommet are all included with this sensor.
