AI Thread Summary
Extending the range of a proximity RFID tag is challenging, particularly with passive tags, which require close proximity to a reader. Suggestions include building a small micropower transmitter to broadcast the tag information, allowing for remote activation. However, concerns arise about signal clarity and how to differentiate the RFID card's signal from background noise. Using an RFID reader to capture the card's contents is essential for this process. Ultimately, achieving a reliable long-range solution for passive RFID tags may require innovative approaches or technology.

Hey guys...not sure if this is possible but is there a way to extend the range of a proximity RFID Tag. I'm looking for a way to broadcast the tag information so i don't have to walk up to the reader with a proximity tag. I'm trying to find a way to open my apartment gate by driving up to it instead of rolling down the window and scanning it. Any ideas?

Build a small micropower transmitter that outputs the rfid codes.
 
How would you be able to pick out the signal from the RFID card?
 
Use an RFID reader to get the card contents.
 
Hi,

Is that a passive or an active tag?

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
