The HLK-LD7901B operates on the Frequency Modulated Continuous Wave (FMCW) principle within the 79-81GHz band, enabling it to achieve millimeter-level accuracy even in challenging environmental conditions. Its high-frequency, narrow-beam design minimizes interference from tank walls, foam, or surface turbulence, ensuring stable and reliable readings.
This sensor module is fully integrated, housing the RF front-end, signal processor, and control logic on a single board. It outputs processed distance data via a serial communication interface (typically UART), making it directly compatible with most industrial control systems and microcontrollers without requiring complex external signal conditioning.
