Week -2

1. Simulink model of Doorbell using solenoid block

This simulation making with help of matlab R2022a simulink library blocks are:

• Pulse generator
• Scope
• Battery
• Solenoid
• Mechanical translational reference
• Electrical translational reference
• Switch
• PS - simulink converter
• Simulink - PS converter
• Ideal translational motion sensor
• Solver configuration

Operational parameters from pulse generator in closing time and releasing times are 2+2=4 sec,

This procces are again and again contineously.

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

Temperature source by,

• 20 °C from 0 to 10 seconds,
• 27 °C from 10 to 30 seconds,
• 23 °C from 30 to 50 seconds

Fan conditions: ON if the temperature above 25 °C,

OFF Condition: When It's raising 70 °C off condition accure at heater High temperature as soon as possible.
