1. Plug and play, easy assembly 2. The sensing distance can reach 9 meters, with configurable closest and farthest detection distances 3. Wide detection angle with coverage up to 75 degrees 4. Multi-level intelligent parameterization to adapt to changing environments 5. Visual debugging and configuration tools LD2412 is a high-sensitivity 24GHz human presence sensing module. It operates using FMCW (Frequency-Modulated Continuous Wave) radar technology to detect human targets within a designated space. Combined with radar signal processing and advanced human body sensing algorithms, it enables high-sensitivity detection of both moving and stationary individuals, while also calculating auxiliary data such as target distance. This product is designed for indoor applications, detecting the presence of moving or slightly moving humans within the sensing area and providing real-time output. Maximum sensing distance reaches 9 meters with a distance resolution of 0.75 meters. A visual configuration tool is provided for easy setup of sensing range, sensitivity across different zones, unattended delay time, and other parameters to suit various application requirements. Supports GPIO and UART output, offering plug-and-play functionality for flexible integration into diverse smart environments and end devices. Compact and streamlined design supports ceiling or wall mounting. Operates in the 24GHz ISM band.
