Respiration & Presence Sensor System

by Exceed Technology


Our sensor system is a seamless integration of the XeThru UWB radar SOC with custom DSP and WIFI wireless communication, complete as an encapsulated end product. It comprises signal processing, embedded control libraries to measure very minute movements like human respiration and other vital signs. Data are then communicated via standard TCPIP to any receiving service for advanced data processing.

Sensor modules by XeThru


Human presence detection


  •  The sensor detects human presence and any type of movement in a room, as well as measures the distance to the target.
  •  Sensor output includes movement metrics, object distance as well as baseband data

Advanced Respiration and Movement


  • The sensor provides advanced respiration and movement tracking both during the day and throughout the night.
  • Ideal for sleep analysis when used together with the XeThru Sleep Analysis Library running on a host

With your choice of microcontroller


  • The X4M05 is a complete radar sub-system containing the X4 UWB Impulse Radar SOC and antenna
  • SPI Interface to the host.
  • Ideal for data processing on external MCUs
