Wide-Angle Human Presence Sensor with 9m Range and USB-C Connectivity"

Introducing the HA12, a high-sensitivity human presence and motion detection sensor with an extended range and wide-angle coverage. Built on the Hi-Link HLK-LD2412 24GHz radar module, the HA12 combines advanced radar sensing technology with TotalSense LLC’s plug-and-play enhancements for superior usability and precision.

Using FMCW frequency modulation continuous wave technology, the HA12 detects human targets in both motion and stationary states while providing auxiliary data such as target distance. With a maximum sensing range of 9 meters and a wide detection angle of ±75°, it’s ideal for larger indoor spaces and advanced smart home applications.

Key Features:

• Extended Detection Range: Senses human presence up to 9 meters with a distance resolution of 0.75m.
• Wide Detection Angle: Covers a broad area with ±75° detection, ideal for expansive indoor spaces.
• Plug-and-Play USB-C Power: Provides a hassle-free setup with no soldering required.
• Bluetooth Integration: Enables seamless configuration and monitoring via a Play Store app or Home Assistant BLE applications.
• Advanced Configuration Tools: Customize sensing range, sensitivity, and delay settings using a visual debugging interface.
• Compact Design: Simplified form factor, supporting wall and ceiling mounting for versatile installations.
• Dual Power Options: Supports both 5V and 3.3V power inputs for added flexibility.

Additional Advantages:

• Environmental Adaptability: Operates reliably in various indoor conditions, unaffected by temperature, brightness, or humidity.
• Target State Output: Configurable GPIO output for high or low-level signals based on presence detection.
• Flexible Integration: Includes UART and GPIO output options for diverse application needs.
• Regulatory Compliance: Operates on the 24GHz ISM frequency band, certified by FCC and CE spectrum regulations.

The HA12 is perfect for smart homes, offices, and commercial spaces requiring precise, wide-area human presence sensing with seamless integration into automation systems.
