This
compact sonar range finder by Maxbotix detects
objects from 0 to 7.65 m with a resolution
of 2.5 cmfor distances beyond 15 cm. Unlike
other sonar range finders, the LV-MaxSonar
has virtually no dead zone: it can detect
even small objects up to and touching the
front sensor
face!

2.1 SensComp Instrument Package
This package combines the SensComp/Polaroid Instrument
Grade Transducer, 6500 Ranging Module, interface
cable, and application notes and specifications. This is a great way to begin
using the SensComp/Polaroid detector for proximity sensing.
2.2
SensComp 6500 Ranging Module
The 6500 Series is an economical sonar ranging module
that can drive all SensComp/Polaroid electrostatic transducers with no
additional interface. This module, with a simple interface, is able to measure
distances from 6 inches to 35 feet. This was formerly made by Polaroid, but is
now made by
SensComp.
