LD2412 Human Presence Sensor Module 24G Wide-Angle Millimeter Wave Radar Detection Module 75° 9M Radar Sensor Module

LD2412 is a wide-angle+long-distance human presence detection millimeter wave radar sensor. Its working principle is to use FMCW frequency modulation continuous wave to detect human targets in a set space. Combined with radar signal processing and precise human sensing algorithm, it achieves high-sensitivity human presence state sensing, can recognize human bodies in motion and stationary states, and can calculate auxiliary information such as target distance. Mainly used in indoor scene perception areas to detect whether there are moving or micro moving human bodies, and to output real-time detection results. Max sensing distance can reach 9 meters with a distance resolution of 0.75m. Provide a visual configuration tool that can easily configure the sensing distance range, sensing sensitivity in different intervals, and unmanned delay time to meet different specific application requirements. Supports GPIO and UART connection, plug and play, flexible application in different intelligent scenarios and terminal products.
