Week -2

1. Simulink Model for Door Bell using solenoid.

Used Solenoid module as a bell, the input supply give with electrical switch whose switching operation is generator with Pulse Generator module and the mechanical component R with respective to C of solenoid where monitored with help of Translation motion sensor.

The Input pulse generator is:

The Ouput recorded as below:

For ever 2seconds the switch is closed and the bell rings ( the mechanical motion R of solenoid is captured with the translated motion sensor).

2. Thermistor to sense the temperature and control the FAN.

Temperature source: 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 otherwise.

The °C is convertered to Kelvin K, the temperature reading would be 293K, 300K & 296K.

The given inputs mentioned above is ploted using repeating sequence wave:

The resistor 100Ohm were used as the trasducer to monitor or sens the temperature changes and the ouput voltage were observed, comnpaired with the given input temperatures and designed the FAN switch operation according to the give requirment, if the temperature above 25 °C FAN -ON, OFF otherwise.

The ON-OFF of the FAN switch is recorded (the output wave):

The requirement is designed and satified by above Simlink Models.
