HLK-LD116-24G USER MANUAL Summary: HLK-LD116-24G is a miniaturized, low-cost 24G millimeter-wave radar sensor used in security, smart home and other fields. Sensor appearance and interface（mm） Sensor features: Working frequency：24G-24.25GHz Equivalent isotropic radiation efficiency（EIRP）：6dBm Phase noise：-96dBc/Hz@1MHz offset Receive noise figure：10dB DSB ... - Page 4 HLK-LD116-24G USER MANUAL Refer to FOV： Scenario 1: Hanging at a height of 3 meters, measuring the sensing range of the module when the human body moves below. It is mostly used for light sense applications. The microwave module has different sensing ranges for positive and tangential movement, and the boundary of the sensing range is particularly obvious.
- Page 5 HLK-LD116-24G USER MANUAL Scenario 2: The radar module faces the human body at a height of about 1.2 meters to measure the sensing range of a person moving in front of the radar module. This scene is mostly used in smart home appliance sensing, access control panel triggering and other fields.
- Page 6 HLK-LD116-24G USER MANUAL Block time The blocking time refers to the time from when the current detection is completed and the output level returns to 0 level until the next detection takes effect. This time can be adjusted by changing the resistance of R8.
- Page 7 HLK-LD116-24G USER MANUAL Trigger delay adjustment The high level maintenance time after triggering is the maintenance time for the module to output 3.3V high level after detecting a moving object. The output delay time can be adjusted by changing the value of R14, the corresponding relationship is shown in the following table: R14（KΩ）...
