2. System description
HLK-LD2410S is a battery-powered ultra-low-power millimeter-wave sensor based on Hi-
Link's millimeter-wave sensor chip. The sensor uses FMCW FM continuous wave, radar signal
processing and built-in intelligent low-power body sensing algorithm to detect the human body
target in the set space and update the detection results in real time. With this millimeter-wave sensor
reference solution, users can quickly develop their own precise, low-power body sensing products.
The hardware LD2410S is mainly composed of a fully integrated intelligent millimeter wave
sensor SoC, a 24 GHz antenna and a main control MCU. The software part is combined with the
low-power human presence sensing algorithm firmware and visual configuration tool released by
Hi-Link to realize the human body sensing function that can flexibly configure sensing distance,
trigger and hold thresholds, unreported time and data refresh rate.
