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
