Week -2
1. Doorbell
Report-
- Doorbell is created by using a solenoid.
- Input signal was given by pulse generator.
- signal is converted using Simulink to PS converter.
- signal is passed to a switch connected to a battery which is connected to an inductor.
- solenoid is connected to a motion sensor.
- electrical reference is added to the first half to provide a reference. similarly, mechanical reference is added to the second half.
- input
- output signal
2. thermistor-fan
Report-
Right mark shows that at temp below 298.15 after 50 sec(23' C) switch is off i.e fan is off
- Signal builder is used to generate signals for 3 different inputs. as shown
- threshold value was found by giving input of value 298.15
- Threshold value was set for the switch.
- essential connections are made for the circuit.
- output obtained is
- where 1 stands for switch on and 0 stands for switch off.
