Our version of the ZY-M100 detector uses 24GHz radar technology

The main difference between human presence detection using 5.8 GHz and 24 GHz radar lies in the system's accuracy, range, and sensitivity. Below, I explain their key differences:

1. Frequency and Accuracy

• 5.8 GHz Radar:

  • Lower frequency, which implies a longer wavelength.
  • Less accurate in detecting small movements.
  • Greater interference with other devices that operate on similar frequencies, such as WiFi or microwaves.
  • Reduced ability to detect static presence (immobile people).

• 24 GHz Radar:

  • Higher frequency, which means a shorter wavelength and greater accuracy.
  • It can detect even micromovements, such as breathing or heartbeats.
  • Improved performance in complex environments with multiple objects.
  • Less interference with other electronic devices.

2. Range and Sensitivity

• 5.8 GHz Radar:

  • It generally has a range of 3 to 8 meters depending on the power and environmental conditions.
  • More sensitive to large moving objects, but less effective at detecting static presence.

• 24 GHz Radar:

  • Greater range, usually up to 10-15 meters with better accuracy.
  • It can detect human presence even if the person is still, thanks to its ability to pick up breathing signals.
  • Greater penetration capacity in materials such as thin walls or glass.

3. Applications and Use

• 5.8 GHz: Commonly used in motion sensors for automatic lighting, basic alarms, and indoor presence detection.
• 24 GHz: Used in advanced security systems, home automation, access control, vital signs measurement and occupancy detection in vehicles and offices.

Conclusion

If you're looking for a more affordable, basic sensor for activating lights or simple alarms, the 5.8 GHz is a good option. But if you need greater accuracy, motion detection, or a more advanced system for automation and security, the 24 GHz is the best choice.
