Microcontroller homework for week 05 1. Treshold, sensitivity, (full) range, linearity, accuracy, precision, stability, hysteresis, noise 2. VO = RH/(RT+RH) = 0.381356 V 3. A) 100 B) 212,464 4. A) B) R1 = 16,67 k C) D) E) RF = 10k, RL = 28k2, RH = 107k F) Before scaling: 2.35 steps/°C. After scaling: 3.42 steps/°C 5. Some things were assumed, as they were not given. 30 = 1,13V 40 = 0,976V So 35 should be between 40 and 30. Assuming about 1,053 V. Same for 5 degrees... Assuming about 1,725 V. 35 degrees digital 1,053/10*1024 = 107,8272 5 degrees digital 1,725/10*1024 = 176,64 177 108 = 69 ADC counts, 30 degrees SPAN 69/30 = 2,3 ADC ...
