Aquatic Spectrometer & Turbidity Meter ECE 4007 L1 Paul Johnson Daniel LundyJohn ReeseAsad Hashim
Overview • Introduction & Background • Project Description & Goals • Technical Specifications • Design Approach • Schedule • Marketing & Cost Analysis • Current Status
Introduction & Background • What is it?A device to detect the colour and clarity of a uniform flowing water sample • How will it work?LEDs, a diffraction grating, a photodetector array and an on-board PC • Why do we need it?Demand from Aqua-culturists and Water Regulation Authorities for a cheap and easy to use device
Project Description & Goals • Goals • A low selling price of $1499.99 • A small overall product size • Universal PVC connectors for easy installment • Real time measurement capability • Ability to autonomously calibrate • An output which is easily connected to a PC • PC Drivers and software capable of analyzing and recording measurements made by the device
4-beam continuous ratiometric measurement 50 – 1000 Nephelometric Turbidity Unit (NTU) detection Diffraction angle detection for color recognition Specifications: Turbidity/Photospectography Detection 1 1 2
10Base-T Ethernet port Opto-isolated digital I/O embedded communication Web based remote management Specifications: Interfacing 3 4
Specifications: Physical • Flanged aluminum enclosure • ¾” Male National Pipe Tapered (NPT) connections • Acrylic sampling tube 5 6
Current Products • Turbidity Meters (~$800s - $1000s) • Advantages • Cost Less than Spectrometers • Small and Portable • Disadvantages • Cannot do color detection on samples • Usually implement detection by use of vials (not real-time analysis) http://www.globalw.com/images/products/tc3000.jpg
Current Products • Mass Spectrometers (~$100,000s) • Advantages • High resolution detection of a sample’s color content • Very Accurate and Stable System • Disadvantages • Not a real-time analysis • Bulky and Not portable • Very High Cost http://chemistry.gsu.edu/facilities/Q-TOF.jpg
Current Products • Mini Spectrometers (~$2000s) • Advantages • Cost Effective Solution to Mass Spectrometers • Compact Size • Can be implemented to do real-time analysis • Disadvantages • Cost More than Turbidity Meters • Lacks some resolution and accuracy to mass spectrometers http://oceanoptics.com/images/Spectrometers/hr4000_large.jpg
Our Product • Advantages: • Real-time analysis • Small and Portable • Cost effective solution to color spectroscopy and turbidity measurements • Disadvantages • Probable Low Resolution
Marketing & Cost Analysis • Currently available meters are: • Expensive • Unnecessarily Complicated 7
Marketing & Cost Analysis • Development Costs:Parts: $420 Labour: $50,000 • Final Price: $1499.99 • Includes parts, marketing, overhead, labour, testing and assembly • Expected Revenue: $374,998 • Expected Profit: $74,741 (19.9%)
Current Status We are currently scavenging scanners, copiers and all manner of electronic devices for linear photo detector arrays. Source: Office Space (1999, 20th Century Fox)
