LD2410C is a high-sensitivity 24 GHz human presence sensing module. It operates using FMCW (Frequency Modulated Continuous Wave) radar technology to detect human targets within a defined space. Combined with radar signal processing and an advanced human body sensing algorithm, it enables highly sensitive detection of both moving and stationary humans, and can estimate target distance and other auxiliary information.The module is designed primarily for indoor use to detect human movement or micro-movement in real time. Maximum detection distance is up to 6 meters, with a resolution of 0.75 meters. A configuration tool allows adjustment of detection range, sensitivity across different zones, and unattended delay time.It supports GPIO and UART output, features plug-and-play functionality, and is suitable for integration into various smart devices and applications.Color: Blue Material: Plastic + Metal Frequency: 24 GHz – 24.25 GHz Modulation Method: FMCW Detection Distance: Adjustable from 0.75 m to 6 m Detection Angle: ±60° Power Supply: 5 V Operating Current: ~79 mA Output Logic Level: 3.3 V Sweep Bandwidth: 250 MHz Operating Temperature: -40 °C to +85 °C Data Output Format: ASCII via UART / Digital high-low level (3.3 V / 0 V)Package Contents: 1 × Sensing Module Note: Color appearance may vary slightly due to lighting conditions and display settings.
