f 24G Smart Home Human Distance Sensing and Gesture Recognition Module

LD2411 is a human distance sensing and gesture recognition module that can recognize the user's gesture lifting and lowering actions, as well as detect the user's actions of entering and exiting the toilet. It outputs GPIO signals through the detected actions, allowing the manufacturer's single-chip microcomputer to control the opening and closing of the toilet lid. The module is powered by 5V, and the radar beam adopts a wide and narrow alternating design. The horizontal angle (4 patches) is about ±20°, and the vertical angle is ±40°. The antenna placement direction is adjusted according to the scene. For toilet applications, it is recommended to use a narrow horizontal beam to avoid false triggering when the human body passes by. The LD2411 module integrates 24G radar and BLE5.0 Bluetooth, with low unit price and high cost performance. It has mature cases in smart toilets and can realize functions such as automatic switch by sensing the human distance, gesture recognition control, and smart flip. In addition to its application in smart toilets, it can also be well applied in other smart home appliances, smart lighting, etc., such as gesture switch lights, non-contact screen lighting and other application scenarios.
