Description

This mmWave radar module utilizes a 24GHz Frequency Modulated Continuous Wave (FMCW) signal and advanced Doppler processing to detect human presence, micromotion, and specific fall events within a defined area. Its millimetre-wave technology allows it to sense through certain non-metallic obstructions, making installation flexible and maintaining functionality where optical sensors would fail.

The onboard standard algorithm distinguishes between occupied and unoccupied states, identifies human activities, and triggers a dedicated output for fall detection. With low output power (10 dBm), it is safe for prolonged human exposure. The module is designed for high robustness across varying environmental conditions including temperature, humidity, and light interference.

Key Features

  • Core Technology: Infineon Technologies 24GHz FMCW Industrial Radar Chipset
  • Advanced Detection: Singular fall detection, micromotion sensing, and occupancy state monitoring
  • High Accuracy & Reliability: >95% detection accuracy with reduced non-living object interference
  • Environmental Robustness: Operating temperature range of -25°C to +60°C; functions in complex conditions
  • Privacy by Design: Provides surveillance capability without capturing identifiable visual data
  • Flexible Antenna Pattern: Fan-beam coverage with Horizontal 90°/Vertical 60° field of view
  • Developer-Friendly: Supports secondary development for customizing radar parameters and protocols
  • Safe Operation: Low output power (10 dBm) ensures it is harmless for prolonged human exposure.

Applications

  • Elderly Care & Remote Health Monitoring: Automated fall detection in private residences or care facilities.
  • Smart Home Automation: Privacy-sensitive occupancy sensing for lighting, HVAC, and security systems.
  • Hospitality & Hotel Room Management: Detecting guest presence and potential emergencies without cameras.
  • Industrial Safety Monitoring: Worker presence and abnormal activity detection in restricted or hazardous zones.
  • Assisted Living & Institutional Care: Monitoring patient activity and generating alerts for staff in privacy-compliant environments.

Frequently Asked Questions

What is the operating voltage and current requirement for this radar module?

The module requires a DC supply voltage between 4.5V and 6V. During normal operation, it draws between 90mA and 100mA (ICC). The digital I/O pins can sink or source up to 20mA each.

How does this mmWave sensor detect falls, and what is its accuracy?

It uses 24GHz FMCW radar and an enhanced Doppler processing algorithm to analyze human motion patterns. It is specifically tuned to identify rapid descent and abnormal inactivity associated with a fall event, with a claimed detection accuracy exceeding 95%.

Can the sensor operate through walls or obstructions?

The 24GHz millimetre-wave signal can penetrate certain non-metallic, low-density materials (like drywall or clothing), allowing for flexible installation. However, metallic objects and dense materials will block the signal. Its primary design is for in-room monitoring, not through-wall detection.

Is this sensor suitable for outdoor use or harsh environments?

Its operating temperature range is -25°C to +60°C, making it suitable for many indoor and sheltered outdoor applications. While robust against environmental factors like humidity and air currents, it is not specified with an IP rating for waterproofing, so direct exposure to rain should be avoided.

Does the module support customization or secondary development?

Yes, the module supports secondary development. Developers can access and modify radar parameters, communication protocols, and potentially antenna configurations to tailor the sensing behavior for specific applications beyond the pre-programmed fall detection algorithm.
