Assignment ) Develop a Sensor Circuit using commodity components
The first part of the assignment is to design a prototype of home security system with passive proximity sensor, light sensor, temperature sensor and examine its performance.
Note: You have to demonstrate the working of the circuit by the deadline. Report will be submitted with the second part of the assignment.
Youare to design the security system with the proximity, light and temperature sensors. All sensors should be incorporated in one big circuit and if any sensor senses an intruder then it should trigger an alarm. The alarm could be flashing of LED or a speaker in the prototype circuit. The circuit should be designed and demonstrated . You should have a schematic of your circuit during demonstration. This prototype circuit will be used in the wireless part of the assignment. Therefore, you should keep it in a safe place for later use.
The report should address following topics
The report should also provide the recommendation as how to implement your prototype circuit in real time to provide home security. The justification for real-time circuit should be in terms of extra components, voltage and current requirements. In addition, state issues related to the practical implementation of the system and provide the possible solutions.
A clever student notices that a high constant loop gain would make the PLL converge in frequency and phase. Rather than use an amplifier with infinite gain the student decides to just use an unstable filter.
Determine the Fourier Series Coefficients Ck for the output y(t) ofan LTI system with impulse response h(t)=e^(-t) u(t) to the inputx(t)=cos2t + sin3t
