Answer to Question #305445 in Engineering for Hell No

Question

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

(Digital 1): This unit tracks the speed of the fan. • Measure the motor speed speed (rpm) using appropriate external sensors.

• Display the speed and temperature using multiplexed Seven Segment Display (SSDs). The temperature should be obtained from the Speed Reference unit.

(Digital 2): 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.
