Radar transmits and receives electromagnetic waves to determine the presence of a human body. The closer you are to the radar, the higher the accuracy.
Phenomenon 1) The human body is outside the radar range
Please refer to the radar scanning range, and adjust the installation angle; the radar measurement range, in different environments, the electromagnetic wave reflection area is different, and the scanning area will be slightly different.
Phenomenon 2) Metal occlusion causes wrong output
Too thick office chairs and metal seats will block the penetration of electromagnetic waves and cause misjudgment.
Phenomenon 3) Difference in scanning angle
The radar did not scan the torso, resulting in a misjudgment.
Phenomenon 4) Radar sensitivity is too low
Radar provides parameter adjustment to increase sensitivity improvement.
