Fall Detection System Using mmWave Sensor

Passive-Infrared (PIR) sensors have traditionally been used as motion detectors, but their effectiveness is restricted by a small area of coverage and an inability to discern between the presence and absence of living beings. As a result, they frequently require user-adjusted cut-off timers for simple automation jobs. While there are other ways to detect human presence, they are either more expensive to deploy or more invasive. But this picture has completely changed with the introduction of contemporary mm Wave Smart Sensors that use Frequency Modulated Continuous Wave (FMCW) radar technology. These advanced sensors offer precise differentiation between the presence and absence of living beings, ushering in a myriad of new applications. Notably, they remain unaffected by varying lighting conditions, inclement weather, or dust, ensuring consistent performance across diverse environments. Moreover, certain models of these smart sensors boast capabilities for non-contact and non-intrusive monitoring of human vital parameters, further expanding their utility. These smart sensors' digital tunability, which makes it simple for loT developers to adjust complex parameters, is one of their main advantages. This increases their adaptability and simplifies their integration with other apps and systems. In terms of environmental sensing and human presence detection, mmWave Smart Sensors mark a substantial advancement because to their increased performance, dependability, and versatility. Their widespread use is expected to spur innovation in a variety of sectors, including healthcare and home automation, and will usher increased comfort, safety, security and efficiency.
