I am sorry but this is all I have. I looked up the definition of RFID-Inductive coupling: from the definition below could anyone tell me in layman's term (still learning) what the hall sensor function is? I apologize in advance for my inability to convey this system "... the reader's antenna...

Well I don't think I have the proper circuit diagram; Its basically a battery powered lighter with wireless communications that illuminated different color LEDS I am assuming the Hall Sensor used is to detect the magnetic field created by the radio frequency but I am not sure of its function

I was told that this hall sensor is the component that sends the signal to turn on the LED's ; But, I believe this is incorrect since the presence of the RFID that is sending RF which would be the component that initiates the signal to turn on the LEDS?

Apologies, this is all I have and that is the question...how is the hall sensor or one could use an inductive coupling that is adjacent to RFID functioning in this block diagram?? It " senses receipt of the beacon signal' ... I guess that is my question...what does "sense receipt of beacon...

do I need the hall sensor?

Ok, if I have a transceiver circuit comprised of a RFID(with antenna-resonating to RFS) that has the capability of tag-tag communication and the RFID responds to a beacon signal from a RF source by transmitting in response to the beacon signal 2 (alive signal). Its electrically connected so as...

Thank you!

Wow, thank you for this info! But, you Nsaspook, said that a hall effect sensor,(only if it is very close), be used in this gadget that uses RF signals The definition of the hall effect sensor that I have is the following: "A Hall effect sensor is a transducer that varies its output voltage in...

Thanks for the input but I am still not clear on the difference between electromagnetic radiation and electromagnetic fieldIt seems from textbooks definition that radio waves are a type of electromagnetic radiation. From your definition, my inference is that a EMF is a separate component:” RF...

I am confused with the definitions of electromagnetic fields and electromagnetic radiation Are these 2 forms the same thing or different? Is radio waves an electromagnetic field or is it electromagnetic radiation? I read that electromagnetic radiation consists of electric and magnetic fields...

Are Radio Waves a form of electromagnetic field?

I need help explaining that this assumption is not correct or correct: A product uses Radio waves to turn on a LED. Radio waves can be a form of electromagnetic fields therefore, a Hall Effect sensor could be used in this device to turn on that LED.
