C1001毫米波人体探测传感器

概 述

C1001毫米波人体检测传感器是一款采用60GHz工作频率的毫米波雷达，与普通24GHz毫米波只能检测存在、速度、距离不同C1001毫米波人体检测传感器可以实现更多精细的检测功能。

跌倒检测功能

C1001毫米波人体检测传感器达可以通过点云成像算法实现人体姿态识别，对平躺状态有准确探知；并进行精准生命探测，对跌倒状态、停留时间，身体静止驻留状态都有准确上报。

接口介绍

睡眠检测功能

C1001毫米波人体检测传感器可以实现对人体生物存在感知及人体运动感知，持续记录人体存在情况，根据睡眠过程中的身体运动幅度变化和呼吸心率变化，对目标的睡眠状态、呼吸心跳频率进行实时判断，在一段睡眠过程结束后输出睡眠评分，根据相关睡眠参数的输出结合到健康康养的应用上。
