Description
Overview
GAOTek Breath Detection Microwave Motion Sensor is the human presence detection sensor radar module based on 5.8 GHz frequency modulated continuous wave (FMCW), which is used to detect human movement, micro-movement, breathing signals. And the overall power consumption can reach 20 MA. It provides measured range information and can avoid false triggers and interference outside the set range better.
Features
