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.
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.
2. Metal occlusion causes wrong output.
Too thick office chairs and metal seats will block the penetration of electromagnetic waves and cause misjudgment.
3. Difference in scanning angle.
The radar did not scan the torso, resulting in a misjudgment.
4. Radar sensitivity is too low.
Radar provides parameter adjustment to increase sensitivity improvement.
