The Design of the management system for parking lot based on 2.45GHz active RFID

The application of RFID technology on parking lot make it effective, convenient and safe. An active 2.45GHz RFID system based on MSP430 series MCU and nRF24L01 low power radio transceiver chip is introduced in this article with emphasis on the system's hardware design, realization scheme of anti-collision algorithm and realization of tag's low power consumption. This active RFID system designed in this article can be used as automatic identification remotely.
