Outline
Infrared thermometers have many useschecking mechanical equipment or electrical circuit
breaker boxes or outlets for hot spotschecking heater or oven temperaturecalibration and control purposesdetecting hot spots / performing diagnostics in
electrical circuit board manufacturingchecking for hot spots in fire fighting situationsmonitoring materials in process of heating and
coolingresearch and development or manufacturing quality
control situationsRedundant to have a separate device
Introduction
Infrared thermometer accessory for smartphonesCase equipped with necessary components
Same physical principles as a hand-held infrared thermometerlens focuses infrared thermal radiation onto
detectorconverts radiant power to electrical signalsignal compensated for ambient temperature,
displayed in [F, C, K] using application
Proposed Idea
Planck Radiation Law
Stephan-Boltzmann Lawderived from Planck's radiation law by
integrating over all wavelengths
Wien’s Displacement Law
Proposed Idea
Top-level diagram
Functional Description
Does not include case; not really a “function”

Design 2:
Considered Designs
Not a health or safety issue
Not a necessity
ROHS compliant
Environmentally Friendly
Manufactured components should come in bulk
Design Constraints
Should have a UL certificationElectrostatic discharge compliantElectromagnetic compatibility compliant
Software responsibilitiesPersonal information kept secureBe able to identify possible threats within the
program
Professional Responsibilities/Ethics
Infrared thermometer has many uses
