Week -2

1. Make a Simulink model of Doorbell using solenoid block with the following details:

To create a doorbell model using a solenoid block we need to import both the electrical and mechanical systems together.

The list of items used for making a doorbell model:

1. Pulse generator
2. Simulink to ps converter
3. scope
4. open-close switch
5. battery
6. solenoid
7. solver configuration
8. electrical reference
9. ideal translational motion sensor
10. Mechanical Translational
11. Ps -Simulink Converter

2. Use a thermistor to sense the temperature of a heater & turn on or turn off the fan as per below conditions:

To create a thermistor model to sense temperature and cutoff we need to have thermal and electrical system together

The simulink blocks used are

1. Signal builder
2. COntrolled temp source
3. thermal refernce
4. thermistor
5. resistor
6. Voltage source
7. Voltage sensor
8. Switch
9. display
10. scope
