Its working principle is to use FMCW frequency-modulated continuous wave to detect human targets in the set space. Combined with radar signal processing and accurate human body sensing algorithms, it realizes high-sensitivity human presence status sensing, and can identify human bodies in motion and stationary states. And auxiliary information such as the distance of the target can be calculated.<\/span><\/p>\n<p class=\"MsoNormal\"><span style=\"font-size:20px\">This product is mainly used in indoor scenes to sense whether there is a moving or micro-moving human body in the area, and output the detection results in real time. The farthest sensing distance can reach 5 meters, and the distance resolution is 0.75m. Provides a visual configuration tool, which can easily configure the sensing distance range, sensing sensitivity in different intervals and unmanned delay time, etc., to adapt to different specific application needs.<\/span><\/p>\n<div><\/div>\n<div><\/div>\n<div><span style=\"font-size:20px\">\u00a0 Support GPIO and UART output, plug and play, and can be flexibly applied to different smart scenarios and terminal products.<\/span><\/div>\n<table style=\"border-collapse:collapse\" cellpadding=\"0\" cellspacing=\"0\">\n<tbody>\n<tr>\n<td style=\"width:55.4px;height:0px\" width=\"55.4\" height=\"0\">\n<p><\/p>\n<\/td>\n<\/tr>\n<tr>\n<td>\n<p><\/p>\n<\/td>\n<td>\n<p><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<div><\/div>\n<div><img decoding=\"async\" src=\"https:\/\/samama.qa\/wp-content\/uploads\/2026\/06\/kf-S437ecac799b245c7b68da8129504abb6w.webp\" \/><\/div>\n<div><\/div>\n<p style=\", Roboto, Arial, Helvetica, sans-serif, SimSun;font-size:14px;font-weight:400;letter-spacing:normal;line-height:inherit;text-align:left;white-space:normal;margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px\" align=\"left\"><span style=\"font-size:26px;, times, serif\"><strong>2.
