Motion sensor based on Doppler radar

The OKY3065-6 is a highly effective motion sensor that utilizes advanced Doppler radar technology at 10.525GHz. This sensor reliably detects moving objects by emitting microwave signals and analyzing the frequency shift in the reflected waves, leveraging the Doppler effect for accurate motion detection.

Key Features

- Non-Contact Detection: Detects motion without requiring any physical contact.

- Environmental Independence: Operates reliably regardless of temperature, humidity, noise, air, dust, and light conditions.

- Anti-RF Interference: Exhibits excellent resistance to radio frequency interference, ensuring stable performance.

- Low Output Power: Designed with low output power, posing minimal risk to humans.

- Long Detection Range: Provides an extended detection range of more than 20 meters.

Doppler Principle of Operation

The sensor's operation is based on the well-established Doppler effect. When radio waves emitted by the sensor encounter a moving object, the frequency of the reflected wave changes proportionally to the object's velocity. Specifically, if the object is moving towards the sensor, the reflected wave's frequency increases; conversely, if the object is moving away, the frequency decreases.

Ideal Use Cases and Applications

- Automatic Door Control: Widely implemented in automatic door switches for seamless and reliable operation.

- Security Systems: Integrates effectively into security systems, providing reliable intrusion detection capabilities.

- ATM Systems: Employed in ATM automated video control systems for enhanced security and monitoring.

- Traffic Monitoring: Ideally suited for traffic monitoring and control applications, offering accurate data collection.

- Automotive Applications: Utilized in collision warning systems and car reversing sensors to improve vehicle safety.

- Industrial Applications: Beneficial for liquid level detection and production line material detection, enhancing process automation.

Key Advantages

- Wide Area Coverage: Effectively safeguards large perimeters, providing comprehensive security coverage.

- Fewer False Alarms: Can be precisely calibrated to differentiate between human intruders and other movements, significantly reducing false alarms.

- Adverse Weather Performance: Functions efficiently even in challenging weather conditions such as fog, rain, or snow.

- Integration with Other Systems: Seamlessly integrates with CCTV and other security systems, creating a unified security solution.

- Difficult to Evade: The microwave detection field is difficult for intruders to detect and avoid, enhancing overall security effectiveness.
