2410C 24GHZ Human Presence Motion Sensor Module Support Bluetooth-Compatible APP Sensing Sensitive Radar Module FMCW Modulation
Product Description.
LD2410C is a highly sensitive 24GHz human presence sensing module.
The LD2410C is a highly sensitive 24GHz human presence sensor module, which works on the principle of utilizing FMCW frequency modulated continuous wave (FMCW) to detect human targets in a given space.
The principle of operation is to use FMCW FM continuous wave to detect a human target in a defined space, and combine with radar signal processing and accurate human presence sensing algorithms to realize highly sensitive human presence sensing, which can recognize human beings in motion and at rest, and calculate the distance of the target and other auxiliary information.

Configuration utility description (PC side utility is the same as LD2410)
After connecting the module, open the Configuration Tool without clicking the Start button. When the module is connected, open the Configuration Tool without clicking the Start button or clicking the Stop button after starting, you can read or set the mode parameter information. or set the mode parameter information.
Note: You can not read or configure the parameter information after clicking the Start button. You need to stop to configure.
The distance of the APP should be within the Bluetooth-compatible signal range (< 4 meters);
Bluetooth-compatible function is turned on by default, and can be turned off by serial protocol. If Bluetooth-compatible is turned off and you can't use the serial port, you can turn off the power continuously within 2~3s and then power on the power more than 5 times to turn on Bluetooth-compatible again. If Bluetooth-compatible is off and the serial port cannot be used, power off and on for more than 5 times within 2~3s, then Bluetooth-compatible can be turned on again.
