1.2.Application Scenario
HLK-LD2420The human body induction sensor can detect and identify the moving, standing and stationary human body, and is widely used in variousAIoT
Scenarios, covering the following types:
smart home
Perceive the existence and distance of the human body, and report the detection results for the main control module to intelligently control the operation of home appliances.
Smart business
Identify the approach or distance of the human body within the set distance interval; light up the screen in time, and keep the device always on when the human body is present.
Smart Security
Induction access control, building intercom, electronic peephole, etc.
Smart lighting
Recognize and sense the human body, accurately detect the position, and can be used for lighting equipment in public places (sensing lights, bulb lights, etc.).
2.System specification
HLK-LD2420is based on HilinkS3An intelligent and precise human body sensing sensor developed by a series of millimeter wave sensor chips. sensor
useFMCWFM continuous wave, combined with radar signal processing and built-in intelligent human body sensing algorithm, detects human targets in the set space
And update the detection results in real time. Using Hilink's intelligent millimeter wave sensor reference solution, users can quickly develop their own accurate human body sensing products
Taste.
HLK-LD2420The hardware part is mainly composed of the fully integrated Hilink intelligent millimeter wave sensorSoC,24GHzOne send one receive antenna and main control
MCUComposed; the software part is matched with the firmware and visual configuration tool released by Hailingke to realize the flexible configuration of sensing distance, sensitivity and
Human body sensing function for reporting time.
