PPGard FD502 People Fall Detection Sensor Solution

The Joybien PPGard FD502 People Fall Detection Sensor Solution is an ideal companion for seniors, individuals at risk of falls, and those seeking independence. It utilizes advanced non-invasive mmWave monitoring technology, combined with highly accurate AI-enabled fall detection, to ensure safety and peace of mind. This solution when integrating with a local Cloud Server allows automatic and immediate sending of fall-alert signals to family members and caretakers, enabling immediate action that could save lives.

The PPGard FD502 People Fall Detection Sensor Solution is with elderly-friendly design with no cumbersome wearing device needed, and without seeing image of people in the detection area (thanks to the latest mmWave sensing technology) for a non-privacy invading wireless detection; and families can rest assured their loved ones are protected with peace of mind.

Key Features

• Non-invasive mmWave detection technology.
• AI-enabled fall detection with high accuracy and low false-alert rates.
• Local Cloud Server for immediate remote alert signal access.
• Simple mounting and easy installation.

Benefits

• Ideal for seniors, individuals at risk of falls, and those seeking independence.
• Non-intrusive technology that ensures privacy.
• Prompt fall-alert signals to family members or caretakers for immediate response, potentially saving lives.

Fall Detection Sensing (FDS)

For wireless sensing of people-fall-detection along with people movement & tracking in 3-Dimensional region covering 6m x 6m area without privacy invasion. The sensed people behavior data are with Position X/Y/Z, Velocity X/Y/Z, and Acceleration X/Y/Z parameters suitable for people movement analysis such as standing, sitting, lying down or falling down positions.

 

Installation Instructions

• Mount the PPGard FD502 sensor on a wall, aiming it at the desired detection area.
• Connect an USB-C cable to PPGard FD502 sensor and your edge computer.
• Run the accompanying software for AI computing and analysis of people behavior in the detection area.
• Optionally, set up a local MQTT Server to send fall-alert signals to remote recipients via Internet access on a computer or smartphone.
