Radar Fall Detection Sensor

The VS373 is a Radar Fall Detection Sensor that adopts millimeter wave radar technology to detect falls with high accuracy. It enables non-contact human detection using 60 GHz 4D radar point cloud data and triggers fall alarms. Supporting continuous 24-hour detection capabilities, the device operates stably both day and night without relying on visible light, ensuring 100% privacy protection as no images are captured.

Features

  • High Accuracy Detection: 99% fall capture rate with less than 1% false alarm rate
  • Millimeter Wave Radar: 60 GHz frequency with 24 transmitters and 22 receivers
  • Advanced Monitoring: Multi-bed presence detection, breathing detection, dwell detection, and human in-place detection
  • Contactless Technology: Privacy-respecting operation without wearable devices
  • Detection Coverage: 2m × 2m to 4m × 5m range with 70° horizontal and 140° vertical field of view
  • Installation Height: 2.3m to 3m
  • Local Alarms: Buzzer and LED indicator for on-site notifications
  • Data Storage: Stores up to 1,000 historical entries locally with data retrievability
  • Dual Connectivity: LoRaWAN and Wi-Fi (IEEE 802.11b/g/n, 2.4 GHz) for flexible data transmission
  • Digital Output: 1 × DO interface (60V/1A) for customizable local alarms
  • Milesight D2D Protocol: Ultra-low latency direct control without gateways

Thinger.io Integration

The VS373 Radar Fall Detection Sensor integrates seamlessly with Thinger.io through LoRaWAN connectivity, enabling real-time monitoring of fall detection events, presence detection, and breathing rate data in cloud-based dashboards and IoT applications.

Requirements

A LoRaWAN server is required to communicate the VS373 into Thinger.io. Supported options include:

Alongside, the corresponding plugin for the selected LoRaWAN server needs to be installed in your Thinger.io instance.

Get Started

Installation

Look for the plugin in the Thinger.io Plugin Store and install it in your Thinger.io instance. Once the plugin is installed, a new Product will be created for this device.

Configuration

The Product is already preconfigured. Check that the auto-provision prefix matches the one selected in your LoRaWAN server plugin in Thinger.io, or change it to your preference.

The VS373 supports: - LoRaWAN Modes: OTAA/ABP - LoRaWAN Class: Class C - Frequency Bands: CN470/IN865/EU868/RU864/US915/AU915/KR920/AS923-1&2&3&4 - Network Protocols: HTTP, MQTT (via Wi-Fi)

Usage

Start sending uplinks for autoprovisioning devices and buckets. The device transmits fall detection events, presence status, breathing rate, and alarm notifications through LoRaWAN or Wi-Fi.

This product provides predefined dashboards for monitoring fall events, occupancy status, and breathing detection metrics.

Use Cases

  • Healthcare Facilities: Patient monitoring in hospitals and nursing homes
  • Elderly Care: Fall detection in assisted living facilities and senior residences
  • Home Safety: Independent living monitoring for elderly individuals
  • Rehabilitation Centers: Patient safety monitoring during recovery
  • Smart Buildings: Occupancy and safety monitoring in commercial spaces
