LD2411 24G Radar Sensor Module Smart Home Human Distance Sensing & Gesture Recognition Module Automatic Switch FMC W Modulation

Product Description
LD 2411 is a 24GHz radar sensor module for smart home and bathroom applications.
The working principle is to use FMC W FM continuous wave to detect the human target in the set space.
Combined with radar signal processing, accurate human body sensing algorithms, 

it senses the state of moving objects approaching and moving away, as well as human gesture recognition. 

and human gesture recognition.
Mainly applied to smart toilets, sensing whether someone is approaching/away within 2 metres of the sensing area.
Gesture action recognition within 0.5-1 metre, and real-time output of high and low level signals.
Configuration tools are available to modify the sensing distance range, sensing sensitivity and unoccupied delay time.

Module installation method, toilet application, it is recommended that the horizontal narrow beam, 

in order to avoid false triggering next to the passing human body.
Toilet lid ring for 5 states: unoccupied state (default lid ring closed), 

people to open the lid (under the state of closed lid),
Gesture flip ring (under open lid state), 

person walks to close the lid (under open lid state) 

and person walks to close the ring to close the lid (under open lid ring state).
