ECE 110/120 Honors Lab Proposal
Members: Andrew Chen ( leihaoc2 , ECE 110 ), Daksh Varshney ( dv5, ECE 120)
Introduction
Statement of Purpose:
Whenever we wake up in the morning or our too lazy to turn off the light when we go to bed, we curse ourselves for having to get down from the bed just to turn on or turn off the light. Seeing this as a viable problem, something that we both have experienced greatly, we want to construct a remote controller to automatically turn off or turn on the lights in our room/dormitory.
Background Research:
We will use RF emitter-receiver system (RF Modules) to transmit signal frequencies from our remote to the light sensor (of the light source board) which will give off required output to the Light Switch whether to turn off or on. Besides, our design also can automatically differentiate relative position of two lights and turn off the light which is father (or closer) from the person holding the controller. In such process, we will use a motion sensor to get information about distance between the two and can have a display LED which will glow whenever we press a button on the remote.
System Overview:
We will build a remote (roughly having dimensions of 3”- 5” * 1” – 1.5”). The remote will include an RF Transmitter that will transmit radio waves. Besides this will also have LED across each of our buttons, which will glow when we press that button, indicating the functionality of that button. Currently, we want to have 4 buttons, 2 for RF Transmitter Lights and 2 for Motion/Distance Detection. The motion sensor will be used to tell the direction and distance between two light sources placed close enough and will return an output to the RF Transmitter so to distinguish between those two light sources.
When the Sensor (of the light board) detects the Radio wave it will change the current positioning of the Light Switch (ON – OFF or OFF – ON) which will in turn make the Light Source (LED, LCD, Bulbs etc.) to glow.
Parts Required
- · 2 set of RF emitter-receiver system
- · 2 set of motion sensor
- · RF switch/microwave switch
- · LED or another light source
- · Connecting wires
- · Transistor, diode, resistor (haven’t decided which type we will use)
- · Breadboard and other basic stuff
Challenges
- · Should we use IR or RF for frequency ( for sensors )
- · The Size of the remote
- · Detection of Signal by the light PCB.
- · Type of switch to be used for connection to the light source, which can turn on or turn off as the RF Detector tells it. We were thinking SPDT RF Switch.
