Module 14 - Sensor Devices

Goal:

This module will introduce the concepts of sensors connected to the ROV system.  A wide range of sensors are covered as they apply to ROV systems.

Objectives

Upon completion of this module, the student should be able to:

  1. Calculate the viewing angle of a given camera lens once it is in water.
  2. Waterproof a temperature sensor that can be used as a tool package and collect temperature data with it mounted on an ROV
  3. Send Heading and temperature data to a HMI system
  4. Evaluate/Debate several environmental issues and discuss how ROV technology could help to collect evidence or monitor the sites discussed
