Overview of Millimeter Wave Sensors

Mar 24, 2025

Lecture on Millimeter Wave Sensors

Introduction

  • Presenter: Aaron
  • Focus: Comparison of 18 millimeter wave sensors
  • Applications: Human movement detection (e.g., breathing)
  • Platform: Home Assistant
  • Avoids cloud-reliant sensors for longevity
  • Power: Mostly Zigbee, some Wi-Fi; require smart home hub
  • No battery-powered devices due to active radar usage

Comparison of Sensors

General Considerations

  • Sensors evaluated for presence detection, radar sensitivity, detection ranges, etc.
  • Testing includes response time, accuracy, cooldown periods, and more.
  • Each sensor's compatibility with Home Assistant is discussed.

Specific Sensors

  1. ZY M100S

    • Wall-mounted, modern look
    • Offers radar sensitivity adjustments
    • Not accurate on target distance
  2. Ceiling Mounted Sensor

    • Ceiling installation with spring-loaded arms
    • Accurate target distance measurement
  3. Advanced Features Sensor

    • Includes a 120 dB alarm
    • Multiple alarm modes
    • Lacks target distance entity
  4. Ugly Square Sensor

    • Unreliable detection
    • Minimal features
  5. Smoke Detector-Style Sensor

    • Aesthetic design
    • Advanced settings for presence detection
  6. Corner Sensor

    • 90-degree field of view
    • Works incomplete with Home Assistant
  7. Eyeball Sensor

    • Unattractive design
    • Good target distance accuracy
  8. Lyp Tech ES1

    • Best design
    • Issues with LED indicator
  9. High Link HLK LD2410

    • Bluetooth capable
    • Requires tuning via app
  10. Athom PS01

    • Combo of PIR and millimeter wave sensors
    • Easy Home Assistant setup
  11. Everything Presence One

    • Combines multiple sensor types
    • Needs assembly
  12. Everything Presence Light

    • No PIR sensor, good target distance accuracy
  13. Aqara FP1 and FP2

    • FP2 better than FP1
    • FP2 supports HomeKit
  14. Sonoff Zigbee Sensor

    • Limited functionality in current form
  15. Apollo MSR1

    • Rich features, including CO2 sensor

Testing

  • Response Time: Athom PS01 and Everything Presence Light respond quickly
  • Cooldown Time: Generally good except for some long cooldowns
  • Target Distance Accuracy: Everything Presence Light most accurate
  • Illuminance Consistency: Varied across devices
  • Small Pet Test: Most sensors ineffective

Recommendations

  • Best Value: High Link HLK LD2410 for price, Everything Presence Light for functionality
  • Features: Everything Presence One and Apollo MSR1 are feature-rich
  • Avoid: No-name black box sensor, GS00 due to network issues, and Aqara FP1

Conclusion

  • Detailed examination of each sensor
  • Recommendations given based on performance and value
  • Open to feedback and suggestions for further exploration of specific sensors
