1.SIMULATION MODEL OF DOORBELL USING SOLENOID BLOCK?

• I have to use required blocks like pulse generator,swith,battery,solenoid,ideal translational motion sensor,mechanical translational reference,electrical reference,solver configuration,simulink PS convertor and ps simulink convertor.
• To create pulse generator its electrical inputs and it directly connected to simulink ps convertor for simulink singnal to physical signals
• Switch ,battery and solenoid connected to series directly
• solenoid another part is connect to the ideal translational sensor.
• if put the power to the switch,switch is closed .solenoid is used in practice for tripping the circuit breakers for operating contactors.
• Mechanical translational sensor is receiving elecrical power in the battery pulls the metal arm to hit the bell and create the sounds.
• translational sensor is to use ,if the switch is closed for 2 seconds and then release.

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

• In this task ,i have to use some main blocks like signal builder,controlled temperature source,thermistor,voltage sensor,resistor,switch,thermal reference,electrical reference,constant blocks,and scope.
• build the signals to send CTS.The temperature difference is set by the physical signal port S. A positive temperature difference causes the temperature at port B to be greater than the temperature at port A.
• battery,thermistor and resistor its directly connected into series,and one voltage sensor connected to resistor for resist the voltage drop ana measuring purpose.
• set the temperatue value for signal builder blocks.Temperature source: 20 °C from 0 to 10 seconds, 27 °C from 10 to 30 seconds, 23 °C from 30 to 50 secondsFan conditions: ON if the temperature above 25 °C, OFF otherwise
• constant block is used to switch ON and OFF Conditions,if the conditions 1 is ON and 0 OFF.
