"Heater on when agency switch activated, door is close and sky beneath expression." Therefore, it is translated to bollean equation as H = P.D.T. F (1-Oni P11-0nl Agency D(1-Closed) Door switch Light L (1-On) Sky Light 1 (1-Over) switch s (1-On) H(1-On) Hester Figure 1: Pictorial opinion of an oven All the inputs and output are two-state unsteadys whereby twain agency and heater are solely switches. A opposition sky enlightener (RTD), which is PT100 example, is applied in this arrangement to mete the sky in the oven. The sky sensor operates from 0 to 200 °C and the regard sky is tunable. Please melody that the elongation of RTD sensor wiring is desire sufficient to pickup the din at encircling 300 kHz and clash the sky voltage. Intent a noconsultation plighting tour to transform sky metement to interface after a while the aforementioned arrangement. Furthermore, the noconsultation plighting tour should curtail the din by 90% using low by leak. Provide regularity and compulsory sober kindred and calculations to profession intent agoing origin. The components are granted as follow: - PT100 (Two wires) - Resistors that furnish to E24 resistor consultation (associate to sequel) - Three terminals 5V agency give - 0 - 200 k 2 unsteady resistor - Comparator (voltage generous dispose from 0 - 5 V) - Operational amplifiers -0.5 pF capacitor In overall, the intent of noconsultation plighting tour should fit into the arrangement as professionn in Figure 2. ? ? PT100 integrated in the noconsultation plighting tour. Figure 2: Arrangement diagram to curb the heater, H Marks 24% 40% Marking Criteria Intent low-by leak to curtail the din by 90%.
