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.
In stock in Australia
Our Code: SEN-10008
Communication with the SRF08 is via the I2C bus making it compatible with a wide range of microcontrollers. The address can be changed to allow up to 16 SRF08 sensors to be connected.
The power consumption of the SRF08 has been improved from the original SRF04 now down to 15mA Typ. and 3mA in the automatic standby mode the senser drops into between readings.
A fully timed echo frees the host controller of the job and in addition the SRF08 keeps reading up to 16 echos so more information is available other than the first object to reflect the ultrasonic burst. This can be usefull when attempting to identify a path such as through a door rather than just the first echo from the door frame.
Be sure to check out the detailed technical description by the manufacturer, including the 'Do not connect' pin.
