Product introduction

HLK-LD8001B is a radar induction module developed based on ADT3102 chip, with a single-chip integrated 76-81GHz RF transceiver system, 1T1R PCB high gain antenna, 1MB flash, radar signal processing unit, ARM ®  Cortex ®- M3 kernel. This module is based on FMCW signal processing mechanism, combined with radar signal processing algorithm, to achieve high-precision ranging, suitable for high-precision liquid level and material level measurement.


Product characteristics

  • Radar detection based on FMCW frequency modulated continuous wave signal

  • The measurement distance can reach up to 15m

  • High precision continuous measurement with an error of+/-5mm

  • Antenna -3dB beam angle horizontal 100 °, elevation 80 °

  • Support SPI, Uart, and I2C standard communication interfaces

  • Small size, 35.3*35.3mm, with a pin to pin connection method

  • Flexible addition of lenses to change antenna angle

  • Not affected by temperature, humidity, noise, airflow, dust, light and other environmental factors


Applications

  • Industrial liquid level measurement

  • Non contact measurement of medical acid-base liquids

  • Fuel tank, IBC ton bucket, viscous liquid measurement
