24G Human Presence Sensor Radar Module

LD2410C is a highly sensitive 24GHz human presence sensor module that works based on FMCW frequency modulated continuous wave to detect human movement in a given space; in addition to its sensitivity to human body movement, it can also sensitively detect motionless, sitting and lying human bodies that cannot be detected by conventional solutions. The farthest sensing distance can reach 6 meters, and the distance resolution is 0.75 meters.
It has good environmental adaptability, and the sensor performance is not affected by environmental factors such as temperature, brightness, humidity and light fluctuations.
The 24GHz human presence induction distance detection radar sensor module also supports GPIO and UART ports, as well as Bluetooth function sensor module.

Note: The Bluetooth compatible function is on by default, and it can be turned off by serial protocol. If the Bluetooth compatible is off and you cannot use the serial port, you can continuously turn off the power within 2 to 3 seconds and then turn on the power more than 5 times to turn on the Bluetooth compatible again. If the Bluetooth compatible is off and you cannot use the serial port, turn off and on more than 5 times within 2 to 3 seconds, then the Bluetooth compatible can be turned on again.
