Doorbell using solenoid block
AIM :
To make a doorbell using solenoid block is using simuling module.
DOORBELL CONCEPT :
The concept of doorbell is used to solenoid. A solenoide is a type of electromagnet formed by a helical coil of wire whose length is substantially greater than its diameter, which generates a controlled magnetic field.
the solenoide is a working in coile of electromagnet formed this non magnet metel iron coile. but this eletrical signal is apply accting the electromagnet formed, so this coile canproduce a uniform magnetic field ina volume of space
solenoide is a power supply switch on state time this is magnetic field is linearly absoure the pulenger, so that pulenger is sum munits vibrate presses the bell this function is electricalmechinal moment.
DOOREBELL BASIC CIRUCT
this concept is power source is used to connect to switch and all the compnent is used, major parts and simuling blocks is used in battery and switch, electromagnet block and spring coile of pulenger ,this matel.
CREATE A PHYSICAL MOVEMENT OF SIMULING MODULE:
The simuling module is sum block is used in pulse generator, simuling ps converter, scope this ts all the signal block and next mojer power source and switch, ideal transulation motion sensor and electeicl refrence is used and imprtent bolck of solenoide and machenical refrence, scope and display all the blocks used.
SCOPE : This scope is output block
PULSE GENERATOR : This block is use inpu of amplitude and frequency generator.
POWER SOURCE (BATTERY) : This is input of positive (+) and negative (-) terminal
SWITCH : This is power sourec of electrical cirucute of current flow in the fuction is on and off
SOLENOIDE : this block is electromagnetic device
ELETRICAL AND MECHANICAL REFRENCE : this is refrence of grount souce
IDEAL TRANSLATED MOTION SENSOR : This is sensor using velocity input provider
SIMULING PS CONVERTER AND PS CONVERTER : this is inpu and outpu amplifer block this simulation function scorce connection is used.
SOLVER CONFIGUREATION : this is using mathmatics function is used
. 
this all block is simuling module of the doore bell concept using solenoid. the power source is apply and input is pulse wave generator using 2 second delay of the frequncy. output is time base plse wave plote
SIMULING BLOCK DIAGRAME :
INPUTE SIGNAL OF PLOTE WAVE FROME :
this is input of puls wave gengrator and 2 sce switch of closed and relesed time pulenger is working the valus.
OUTPUT PLOTE WAVE :
this is plote wave of solenoide function of switch close time ane open time scope and display the output
Thermistor to sense the temperature of a heater & turn on or turn off the fan as per the below conditions
THERMISTOR TO SENSE THE TEMPERATURE :
The thermistor sensor is dependency on the resistance value change the temperature. the change in resistance is dependency on the material. the thermistor consider of special type of resistor
this thermistor is semicontector material used instand of matel. so that material of thermistor is solid state device and lorger senstivity, this thermistor is tow type postive temperature coefficent and negitive temperature coefficent. thermistor exhibit the charateristic of resistance falling witht incresing tempurater.
Thermistor is use simuling block is simuling ps coverter battery source, switch thermel refrencr source all the block using input of repeting seqence strain is used.
SIMULING BLOCK MODULE OF THERMISTER
Simuling inpu plote wave
a signal of temperator is thermistor value of first (0 sec move on 293), ( 10 sec = 310 ) in incresining the temperator, next 30 sec = 310 temperator decresing and 40sec = 296 is decresing.
output of the plote simuling signal :
this wave frome is thermistor block 0 state of the output.
plote of simuling wave frome of the result of on contition
conculation :
The doore bell using solinoide of simuling modulation and plote of wave frome result .
thermistor usinu temperature of heater turn on and off condition simuling module and plote the result.
