Microwave Breathing Sensor Module NP SU AP 6.1

Microwave breathing sensor module NP SU AP 6.1 is a RF sensor module designed to detect live objects presence as well as their respiratory and motor activity from up to 1 meter distance. The module is designed for integration into security systems where it is necessary to detect presence or absence of the life sign indicators in a local area of the room. The module is a low-power microwave sensor operating in UWB license free frequency band 6.0 - 8.5 GHz.


Driving Factors for Buying Breathing Sensor Modules


Advantages of the Breathing Sensor Module

  • Small size
  • License free band
  • Localization of the observed object
