Embodiment Construction
[0009] An anti-disassembly active electronic tag is characterized in that it consists of four parts: a power supply, a main control module, a radio frequency module and an anti-dismantle switch, wherein the main control module is connected to the radio frequency module and the anti-dismantle switch, and the power supplies are respectively provided to the main control module and the radio frequency Module power supply. The model of the chip used in the main control module is MSP430F212. The radio frequency module is composed of nRF24L0l, antenna and crystal oscillator.
[0010] In this paper, nRF24L01 is used as the radio frequency chip, which has built-in functional modules such as frequency generator, power amplifier, modulator and demodulator, which can make the circuit design simple. At the same time, nRF24L01 has extremely low current consumption. The current of the chip is only 12.3mA when it works in receiving mode, 11.3mA in 0 dBm power transmission, and only 900 mA in...
