  1. MSP 430 Project ECE 300 Circuits The University Of Tennessee Spring 2007 Group 8 : Alex Melhorn, Alex Hara, Laura Wakeman, David Heise

  2. MSP 430 • Low Power Architecture • 16-bit CPU • 12-bit ADC • Low Cost

  3. Project Board

  4. AD590 • Accuracy • +/- 0.5º C • +/- 0.9º F • Power Range • 4V – 30V • Temperature Range • -55º C -- 150º C • -67º F -- 302º F • Output • 1μA/K

  5. Circuit Diagram

  6. Circuit Diagram 2

  7. C Sensor File Code for the AD590 was provided by Dr. Green. const float A = 0.613, B = 0.2; . . . XIN = A*B*ADC12MEM6; DKEL = (XIN + XIN1 + XIN2 + XIN3)*0.25; XIN3 = XIN2; XIN2 = XIN1; XIN1 = XIN; CDEG = (DKEL - 273.2);

  9. Temp. Change 2

  10. AD22103 • 28 mV/C

  11. Circuit Diagram

  12. Circuit Diagram 2

  13. C Sensor File Code for the AD22103 was orginally produced by Andrew White, James Hamdorf, and James Psihogios. float XIN7 = 24.5, XIN6 = 24.5, XIN5 = 24.5; float XIN4 = 24.5, XIN3 = 24.5, XIN2 = 24.5, XIN1 = 24.5; const float A = 0.0613, A1 = 21.5909, B = 2.41818; . . . sample = ADC12MEM6; XIN = ((sample*A) - A1)/B; SIGK = (XIN + XIN4 + XIN5 + XIN6 + XIN7 + XIN1 + XIN2 + XIN3)*0.125; XIN7 = XIN6; XIN6 = XIN5; XIN5 = XIN4; XIN4 = XIN3; XIN3 = XIN2; XIN2 = XIN1; XIN1 = XIN; CDEG = (SIGK);
