Devantech SRF10 Small Ultrasonic Range Finder


Click for larger image
The SRF10 is a very small high performance sensor that uses sonar to detect objects. It has a much wider field-of-view than the Sharp infrared distance measuring sensors. Interfaces easily with the Mark III or your own robot design. Comes completely assembled - this is not a kit.

The SRF10 is similar to the SRF08, the main difference being the size of the two devices. The SRF10 is significantly smaller; it takes up only 1/3 the volume of its big brother the SRF08. Other differences are:

  1. In addition to the normal ultrasonic ranging function, the SRF08 has a light sensor (CdS photocell) which can be read out over the I²C bus. The SRF10 does not have a photocell.
  2. The SRF08 can detect up to 16 returning echoes, if several objects are at different distances within the field of view. The SRF10 only detects the first echo (nearest object).
  3. In order to save space, the SRF10 does not have mounting holes like the SRF08. You may devise your own mounting, or purchase the ready-made SRF10 Mounting Bracket.

This item can be connected directly to a USB port on your computer using the optional USB to I2C Interface Module.
