  1. Introduction Objective is to create a field deployable automated CO2 and N2O gas trapping device Trapping events occur every four hours Traps replaced after one month Components Flux Chamber Multiple Sub-chambers Desiccant Trap CO2 Chemical Trap N2O Molecular Sieve Trap CO2 Molecular Sieve Trap Rain-water Drop System

  2. System Flow Chart

  3. Part Selection Valves Manual Solenoid Pump Flow Rate: 130 mL/min Insert Solenoid valve PIC

  4. Part Slection Servo Mechanism Motor Fan

  5. Material Selection Materials in contact with the gases must be chemically inert and gas impermeable Outer Casing and Sub-chambers White PVC – avoiding the greenhouse effect Desiccant Trap Nafion Tubing CO2 Chemical Trap 304 Stainless Steel Tubing Carbosorb CO2 and N2O Traps 304 Stainless Steel Tubing Molecular Sieve 5A Tubing PEEK

  6. Fabrication Assembly Criteria – small profile, sturdy, and easy to use Airtight System Fittings and Adapters CAD Drawings Machined in the ME Shop

  7. Design Visualization

  8. Electrical control system • Control of servos, solenoids, circulation fans, pumps • State machine pertaining phases of device operation operation • Error checking • Sensors provide information about device functionality • Allows for quick repair, operation during non critical failures • Governed by Microcontroller

  9. Programmable System on Chip (PSoC) Visual, code-free embedded design C language base Manually edit code CY3214-PSoCEvalUSB

  10. System Power Demands of system Operates unattended for weeks Hours between samples Microcontroller very demanding The external timer Battery decision All-Battery.com

  11. Summary • CO2 and N2O levels will be used to determine impact of farming • This will facilitate carbon credit trading on global scale • Profitable to farmers • Reduces waste • Cost of end product is low • Will promote ecologically friendly farming practices • Questions?
