SRF485 Ultrasonic range finder

The SRF485 is a single transducer ultrasonic ranger, based on our original SRF02 design. The SRF485 uses the RS485 standard for communications, for up to 127 modules on each RS485 bus. The SRF485 features an on-board 5v power regulator which can be supplied from 8vdc to 14vdc. Both power and RS485 signals are supplied to the module via a 10pin IDC connector, making cabling a large number of modules very easy. The Range of the SRF485 is 30cm to 5meters.
