HLK-LD2411 HLK-LD2411 --EngrWorld

The LD2411 is a human distance sensing and gesture recognition module. it can recognise the user's gesture lifting and releasing movements, as well as detecting the user's movement into and

away from the toilet, and outputting GPIO signals through the detected movements to allow the manufacturer's microcontroller to control the opening or closing of the toilet lid.

The module uses a 5V supply and the radar beam is designed in a wide and narrow way, with a horizontal angle (4 patch) of approximately ±20° and a vertical angle of ±40°, with adjustments

made to the antenna placement direction depending on the scenario. For toilet applications, a narrow horizontal beam is recommended to avoid false triggering of the human body passing by.
