Job Type:
Engineering, Electronics
Description:



Hello,
The circuit will operate using one primary switch and between one and four
secondary switches. The circuit will be used within the confines of a motor
vehicle, so power requirements should be kept within the limitations of a car
battery.
The circuit is a security unit by nature. It will consist of
• Primary switch
• One to four secondary switches
• Power light
• Activation light
• Alarm light
• Transmitter
• Receiver
The circuit should perform as follows. When the unit is plugged in, a light will
confirm power is on. When one or all of the four secondary switches are in their
open position the unit is in standby mode “i.e.” when the main switch is closed
or opened nothing happens. When one or all of the four secondary switches are
closed and the main switch is opened an audible and visual alarm will sound and
a signal will be transmitted to a pocket size receiver which will also emit an
audible and visual alarm. The circuit should also have the following attributes,
(1) When one or all of the four secondary switches are closed you will need to
open and close the main switch within a given period of time or the unit will go
into what I refer to as alarm mode, and emit an audible and visual alarm while
transmitting a signal to a pocket size receiver which will also emit an audible
and visual alarm. (2) When one or all of secondary switches are closed the unit
will emit a light which I refer to as activation light.
The circuit and receiver should be design for the smallest housing possible. All
lights, audible device, and jacks for the primary and secondary switches must be
confined to within this housing. I will require a complete circuit diagram, and
parts list.
My profession is mechanical engineering, so although I have some basic knowledge
of electronics and circuit design, I’m sure I would turn what is probably a
simple project for the right person, into a very long and tedious project for
the wrong person (me).
Thank you, and look forward to hearing from you,
