AIM:
*To make a simulink model of doorbellvusing solenoid block with the given details and assumed parameters.
*To use a thermister to sense the temperature of a heater and turn ON or turn OFF the fan as per the given conditions.
OBJECTIVES:
Create a situation where the switch is closed for 2sec and then released,observe the physical movement of the plunger.
SIMULATION MODEL:
EXPLANATION:
-A switch which controlled by the pulse generator to give the input conditions of time,amplitude,etc that is for the total 4 sec of time the switch is turned ON for 2se and OFF for another 2 seconds.
-Connecting a battery source series to the switch assembly for the input current.
-Connecting a solenoid block along with the battery and switch.
-Use a ideal translational motion sensor to sense the movement of plungeron the solenoid blocks.
-A scope is connected anlong with the ideal translational motion sensor to analyse the graphical representation.
-Using solver configuration and mechanical translational reference to complete the model without an error.

OBJECTIVE2:
Use the thermistor to sense the temperature of a heater and turn ON and OFF the fan as per the conditions.
MODEL EXPLANATION:
A signal builder is used to build temperature in required conditions and connected to a controlled temperature source along with thermistor block.Resistor and battery source is connected series with the thermistor to complete the current flow through the circuite.A voltage sensor is provided parallely with the resistor to measure the voltage across the resistor.The output of the voltage values are connected to the switch model which determines the switching ON and OFF of the fan assembly with respect threshold values.
