PAID WORK: Need to physically alter RF keyfob

Community Jobs and Paid Consultancy

Hello,

I am looking to hire someone to create the schematic and BOM for a micro RF transmitter with a vibration sensor instead of a button.

I would like this to fit these measurements: .500X.350X.300. LXWXH.

I was hoping to take the single button RF key fob and modify it to fit these constraints while swapping the button for a vibration switch. It will still need to work with the 315mhz momentary receiver.

Once i have the documents i will have the boards made.

If you can accomplish this, please provide me with an estimate.

Thank you!

Half a mile by 1/3 of a parsec by 3/10 of a micron?

All measurements are in inches.

500 x 350 x 300 INCHES .. that has to be a mistake

I mean that is over 42 Feet tall ... Unless that is supposed to be 5.00" x 3.5" x 3.0" :slight_smile:

you also need to specify the range of vibration you are looking to detect.

Will a simple mercury switch/or weighted pizzo strip do the job or are you looking at picking up micro Gs of movement in 3 DOF.

Drop me a PM and we can chat.

Cheers Pete.

Missed the decimal points in front of all three values, I see.

No. OP needs to learn to post numbers correctly. 0.500 x 0.350 x 0.300.
