Answer to Question #314747 in Electrical Engineering for Fok

Question

Design a system which determines the speed depending ambient temperature. Display should show current temperature and fan speed.

(Digital 1): This unit will determine the speed of the motor.

• Measure the ambient temperature and determine the whether the fan should spin at high(220v),medium (150v) or low speed high (80v). Send an analogue signal for the speed to the Motor Driver unit. 220, 150 and 80 volts are recommended levels.

• Allow the user to set the temperature bounds digitally for the speed settings.

•Send the current temperature value to the Speed Measurement unit.
