Ultrasonic Range Finders

The Devantech SRF02 low cost ultrasonic sensor supports both I2C and serial interfaces. No calibration is required with the new AutoTune algorithms which back the minimum range right up to the transducer ringdown automatically, with a full range of 15cm- 6m. Seperate burst and ranging control is available with new commands. More details...

The SRF05 is realises big advances in design over the previously successful SRF04 with increased flexibility, greater range ( 3cm-4m) and lower cost. It can use a single pin for trigger and echo and includes an echo pulse delay to accommodate slower controllers such as Basic Stamp and Picaxe. More details...

The SRF08 is an advanced ultrasonic range finder that connects over a I2C interface and has a range of 3cm to 6m. Low power consumption, fully timed multiple echos and a bonus built in light sensor. More details...

The SRF10 is a the smallest dual transducer ultrasonic ranger. It has a range of 6cm to 6m and you can connect up to 16 sensors over a I2C interface. Low power consumption, fully timed echo, variable analog gain and a range of 6cm to 6m. More details...

The Maxbotix LV-MaxSonar-EZ1 is a tiny ultrasonic sensor which can detect objects from 0-6.45m (254") and supports pulse width, analog voltage and serial digital output. More details...
