The mmWave Radar Sensor by Seeedstudio provides exit accuracy, 90% drop detection and 90% presence detection. The sensor is resistant to unfavorable operating conditions such as temperature, humidity, noise, air flow, dust and light. The device sends signals with high accuracy, thanks to the use of standard algorithms and a built-in antenna on the board. It is the ideal solution for high-precision, self-regulating, privacy-protected, secure biotechnology radar systems in private property surveillance, fall protection, elderly health care, suitable for home, hotel and hospital use. Designed in such a way that the radar maintains a health-friendly working condition during observation. The radar module uses FMCV monitoring technology which provides privacy protection through surveillance without identification.
