We invite bids for the design of a simple battery powered electronics device with an alarm.
The work we are looking for includes:
Schematic design
component specification (BOM)
PCB layout (optional)
Device description:
Battery powered Motion sensor with audible alarm. When the device is moved an audible alarm will sound.
The design should include a switch to activate the device. Single press to the switch turns the device on which then becomes active after a delay of 2 or 3 seconds.
A long press on the switch turns the device off.
Component cost is a primary concern, followed closely by reliability.
Design shall become copyright of purchaser.
Hi Andy, I am currently working on a project at the moment that uses a motion sensor and an audible alarm so I have up to date experience on interfacing to these devices. Please see PM for more details.
Hi,
I can design an alarm module with switch and battery.
I am a hardware engineer with proven design capabilities from the industrial field.
Please see my private message
I will do it very cheaply , with simple hardware design , I even may not use a micro-controller , It will be simple hardware design .
I'm very great at hardware /electronics.
Lets starts.
I work in an embedded R&D center in electronics. I have an experience of over 5 years in drawing schematics and artwork. I have done a similar project in the past hence i think i can deliver the prototype on time.
approx 4 year experience of electronic circuit design.
Have experience of Designing such alarming system like burglar alarm ,liquid level and over-temperature alarm system.
