specs code
Specs: Code
  • Switch between AD590 and AD22103 by setting a variable to true or false
  • Uses a queue to implement a 6thorder moving average filter
  • Scrolls “reading sensor”if no input is detected
  • Display works with valuesover 200 degrees
results
Results

Heat stimuli added at time 40 and removed at time 120

Note: Tests were run at different times and at different ambient temperatures

issues
Issues
  • Soldering
    • LCD stopped working properly because a MSP430 pin became unsoldered in transit.
  • Ethanol vapor sensor
    • Unable to locate a cheap sensor.
conclusions
Conclusions
  • We learned to function as a team while working on an engineering project.
  • We gained experience building and troubleshooting a temperature sensor circuit.
  • We acquired basic soldering techniques.
  • We learned to program and debug

a microprocessor.
