RFID HF Chip

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello, 

 I'm looking for an rfid chip directly or HF RFID tags, but I would
also single chip, allowing interfacing with some sensors, such as
temperature, accelerometers, etc. .. Basically I'm looking for a chip
that has the I / O ports for external sensors. 

 Something that already exists? or should I build it? 

 Grazias ..

	It sounds like you want to do a lot more than just ID something, which is all RFID is really meant to do. You're probably going to have to build something using a small cheap microprocessor (probably a PIC) that can be connected to a small cheap transmitter and process values from sensors and transmit those an reprogrammed intervals. You can use a transceiver and some extra code to be able to query the microprocessor from your host system, but that will cost more and take more effort.
