Build RFID transmitter and receiver

Guide on how to build my own RFID transmitter and receiver?

Post by C1

You will find them here ...some entities misuse this technology, hence people have become less interested in this as it is invasive. Properly used this technology is an asset, example - inventory or asset tracking and management.

RFID Circuits - DiscoverCircuits.com - Low Power RFID Transponder -  For some time railroad companies have been wrestling with the problem of tracking rail cars.

Need help in RFID circuit - Electro Tech -  need the circuit for RFID receiver and transponder and any useful information regarding RFID. I thought i would use PIC controller to find out the distance b/w the product and the reader.

Build RFID transmitter and receiver

RFID - Wikipedia.org - Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. The tags contain electronically stored information. Passive tags collect energy from a nearby RFID reader's interrogating radio waves.

Fall 2004 RFID Honors Project - RFID can be categorized as low frequency or high frequency and as passive or active. This project looks mainly at low frequency passive RFID because it is the least expensive and the most common.

Low frequency passive RFID works by magnetic induction. A reader device generates an alternating magnetic field from a coil of wire. A tag also has a coil of wire that induces current from the magnetic field. This current provides power to the passive tag. The tag then sends back its own varying magnetic field which is read by the reader device.

Internet and Intranet of Things - IoT

When Intelligent Devices (embedded systems) are privately and securely networked, it is called the Intranet of Things. This is like a Home-Office-Business private closed Cloud. This is ideal for Home and Infrastructure Automation and even Big Business or SMB Automation.

The Internet of Things - IoT is the Superset. It could be Secure and Private but still vulnerable to security lapses and breakdowns. This could send devices, robots and machines Berserk.

In all Networked Environments we have to have fallback arrangements when network fails or is compromised or even slow due to peak hour internet traffic.

Internet and Intranet of Things - IoT

WSN - Wireless Sensor Networks and M2M - Machine to Machine Data Communication;

M2M and WSN is a closed private Intranet network that is used in Manufacturing and Industrial Automation. Here we could use data sync to Interface it with the Web or Internet. This enables passive controls and monitoring of SCADA or Machine Status, yet very Secure.

COR - Collaborative Online Robotics - This is like team work for bots. Big tasks can be accomplished by very small and weak robots. Example - Observe Ants and Bees.

All these only mean Wireless Networked Intelligent Embedded Systems. They could be machines, appliance, robot or gadget. The brain is both on the device and in the Clouds.
