Alarm Circuit

$10-30 USD

In Progress
Posted over 10 years ago

$10-30 USD

Paid on delivery
The circuit should be powered by 12V (both via an internal rechargeable battery or external power source). When the circuit is closed via a switch for more then a certain period of time (still to be defined, lets say 5 seconds for now), it should activate a siren and send a radio signal (at least 100m range) to a remote buzzer. It should be possible via a switch to select what the circuit is going to do when closed (after the 5 seconds): activate the local siren or send the radio signal to the remote or do both. It should also have a led indicator (5 leds) to inform on the battery charge status when a button is pressed. The remote (also to be designed) should receive the signal end then either vibrate or sound an internal siren or do both (selection made with a switch on the remote). The remote should have the battery status indicator too. Kindly provide all the necessary information to go with the project to a prototyping company to have some prototypes made. Please also indicate the specs of each component and what it does. The final board should be kept as simple and economic as possible. Thanks in advance for your time and support

Hello, I know that my Bid is much higher than your budget. I will make a prototype here and send you via UPS courier services (you have to bear the shipment cost). i will provide full design details including Circuit diagrams, PCB files (Gerber files), Bill Of Material (BOM), Firmware of micro controller involved. This will enable you to mass produce this at later stage. Please feel free to contact. Regards.

(Embedded System Designer & PCB Layout Designer) Hello Dear, Prayers for your good health. I hope you will be fine and enjoying. I am Malik Umair Latif, by profession I am Embedded System Designer specialized in Systems design in micro-controller and microprocessor with digital logic design. At Freelancer.com I am unable to get full exposure for my original skills but I had done some daring designing tasks here with good rating. I am a trust worthy service provider without any dispute or false-saying/fraud. I believe in quality of work and dedication towards client and the task. I have thrice read your job description and I am bidding now because I am confident of the solution and understood your requirement. I had a habit to always facilitate the client with cost effective solutions, (probably thats why in return I get good rating from them). Coming to your design, I have two economical choices, to attain accuracy and precision I must have to keep up with micro-controller solution. There are two micro-controllers which are easily available and are low-cost but works super fine, a) PIC b) 8051 (both under my command). Alongwith this I will use RF (Radio frequency module, ROHS Compliant) with provides 300-500 meters good working range. One will be the remote and other will be the receiver (Full Duplex communication). I fear that I am short of characters allowed in proposal, I will not properly explain here. Please do contact me, I have a simple but perfect solution. Malik
