An XeThru X4 sensor can be used to accurately count respirations per minute. Elderly people cared for at home can benefit from a respiration monitoring device that can keep a check on vital signs.
Take a look at this: Neither the heavy sleeper Charlie, or the XeThru X4M200 Respiration Sensor are disturbed by the other application guys having fun. Once Charlie sleeps and remain the closest person, the X4M200 sensor keeps its target in focus and will track the respiration rate and respiration pattern accurately. Still the sensor sees and track all movements in the back as well, be it a large metal locker on the move or lots of movements when the guys have fun. All key data is output and visualized in XeThru Explorer.
Take a look at how the XeThru X4M200 respiration sensor works and how the output data is visualized in XeThru Explorer. The standard sleep and respiration monitoring abilities are integrated in the sensor and provide advanced respiration and movement tracking both during the day and throughout the night. An increased programmable detection range up to 5 meters is a key upgraded feature for the sensor.
Take a look at how the XeThru X4M300 works with our XeThru Explorer. The Xethru X4M300 presence sensor integrates Novelda’s X4 ultra wide band radar chip. Ultra sensitive and with excellent signal to noise performance, the sensor detects even the smallest human movement in a room. What’s more, the sensor’s presence detection zone is fully programmable, and can be configured up to a distance of 9.4 meters. The sensor also accurately measures the distance to occupants.
In this video, as an extension of our previous safety test experiments (https://youtu.be/9tu3Tdbpywg), we present another false alarm test experiments for big machinery using the IR-UWB radar sensor developed at Hanyang University (HYU), Seoul, Korea, in more practical scenarios. Particularly this time, we concurrently compared the performances of our HYU radar with those of the P**v*** radar (a commercial product from Europe). The ranging distance is set to be equally 6 meters for both radars. The HYU radar uses sound and warning lamp together whenever, either right or wrong, detecting objects, while the P**v*** radar uses two-level sound only.
This video shows a real-time 3D positioning and tracking experiment using eight quasi-monostatic IR-UWB radars. Both 1D and 3D Kalman filters are used for the smooth 3D estimations. The algorithm used in this experiment is designed to be computationally more efficient than conventional 3D algorithms so that real-time operations can be feasible, even though multiple quasi-monostatic radar modules are employed.
This video shows another people counting experiments using an IR-UWB radar sensor in an elevator where all four side walls are made of metal. Although there exist severe multipath interferences as well as ping-pong effects of radio signals, we could maintain a reasonable level of accuracy.
