RFID (Radio Frequency Identification)

 
RFID Reader Module & Transponder Tags

The RFID Reader Module is the first low-cost solution to read passive RFID transponder tags.
The RFID Reader Module can be used in a wide variety of hobbyist and commercial applications, including access control, automatic identification, robotics, navigation, inventory tracking, payment systems, and car immobilization.

Features:
Fully-integrated, low-cost method of reading passive RFID transponder tags.
2400 baud TTL serial interface (output only) to PC and host microcontrollers.
Requires single +5VDC supply.
Bi-color LED for visual indication of activity.
0.100. pin spacing for easy prototyping and integration.

 
  RF (Radio Frequency) Communication

 
RF Transmitter & Receiver Module

The 433 MHz RF modules provide a very easy and low-cost method of sending data between microcontrollers or to a PC from 500 feet+ line-of-sight (depending on conditions).

Specifications:
PCB Size: 0.9"x1.9" (without antenna)
Overall Size: 0.9"x3.6" (with antenna)
Power: 5V +/-10%
Current: ~10 mA normal operation, ~3 mA during power down
Data Rate: 12,000 - 19.2 K baud (controller dependent)
Frequency: 433.92 Mhz (UHF)
Transmission: 500 ft+, based on environment conditions.
Both the receiver and transmitter have a power down feature. The receiver has an RSSI signal for strength indication.
