Week -2
DOOR BELL:
explanation :we use blocks pulse generator ,simulink to ps converter and ps switch solenoid,solver configuration,battery,electrical reference,mechanical translational reference,scope.
pulse genarator:we take amplitude 1 and period 4 sec and pulse width 50% because switch is closed for 2 seconds (50%of 4)
we use simscape blocks so we take simulink to ps converter it take inputs from simulink blocks and converts then ps switch,battery terminals are connected to swich and solenoid.solenoid (transfers electrical to mechanical energy)have 4 connections then one terminal connected to switch and other terminal connected to battery and another two connections are connected to ideal translational motion sensor for closing then we use electrical reference and mechanical referances and then solver configuration is used for simscape bloks and scope is used for graphical representation of output.
THERMISTOR:
From given conditions in challange we take repeating sequence block in this we take temperatures in kelvins for temperatures 20,27,23 degree celcius and connected to simulink converter .it is connected to controlled temperature source this block represents an ideal energy source in a thermal network that can maintain a controlled temperature difference regardless of the heat flow rate. this block connected to thermistor (thermal input to electrical )and other terminal connected to ressistor and another one is connected to battery ressistor is connected to battery and voltage sensor (a device that converts voltage measured between any electrical connections into a physical signal proportional to the voltage)also connected to ressistor here we use electrical referance for closing the circuit and solver configuration also used for semiscape blocks switch(pass through input 1 when input 2 satisfies the selected criterion otherwise, pass through input 3) because we give some fan conditions on if temperature is above 25 degree celicius and off other wise.scope is used for graphical representaion of output and ps-simulink converter used for convert physical signal to simulink output
