RFID CARD READER/DETECTOR MODULE KIT- RC522 RFID + S50 Card

RFID (Radio Frequency Identification) sensors are devices that use radio waves to read and write data from RFID tags or transponders. RFID tags contain a small integrated circuit and an antenna, and can be attached to or embedded in objects for identification and tracking purposes.

Here are some ...common specifications for RFID sensors:

Frequency range: RFID sensors operate at various frequencies depending on the application. Common frequency ranges include 125 kHz, 13.56 MHz, and 900 MHz.

Read range: The read range of an RFID sensor depends on the frequency used, the power of the sensor, and the size and orientation of the RFID tag. Typical read ranges can range from a few centimeters to several meters.

Data transfer rate: The data transfer rate of an RFID sensor depends on the frequency used and the amount of data being transferred. Typical data transfer rates can range from a few kilobits per second to several megabits per second.

Antenna type: RFID sensors typically use either a linear or circular polarized antenna. Linear polarized antennas have a longer read range but require the tag to be oriented in a specific direction, while circular polarized antennas have a shorter read range but can read tags in any orientation.

Power source: RFID sensors can be powered by a wired connection or by battery. Battery-powered sensors are typically used in portable applications where wired power is not available.

Data interface: RFID sensors typically have a data interface such as USB, RS232, or Ethernet for connecting to a computer or other device.

Operating temperature range: The operating temperature range of an RFID sensor depends on the specific model, but typically ranges from -20°C to +70°C.

RFID sensors are commonly used in a variety of applications including inventory management, asset tracking, access control, and transportation. The specific requirements for an RFID sensor will depend on the application and the environment in which it will be used.
