Abstract

The present invention discloses an electronic tag with a motion direction detection function. A microprocessor is respectively connected with a power supply module, a radio frequency transmitting and receiving module and a three-axis acceleration sensor module; the radio frequency transmitting and receiving module is connected with an antenna; the three-axis acceleration sensor module adopts an LIS3DH chip; INT1, SCL / SPC, SDA / SDIO and CS pins of the LIS3DH chip are respectively connected with #INT1, SCL, SCK / SDA and +AKPWR pins of the microprocessor; and ADC1, ADC2, ADC3, GND, RES and SAO / SDO pins are respectively grounded. According to the present invention, one three-axis acceleration sensor module capable of detecting the motion direction of an object in real time is integrated on the basis of a conventional electronic tag; the motion state of the electronic tag can be dynamically monitored; cost is low; power consumption is low; and the application range of the active electronic tag can be enlarged to a great degree.
