4.2 Power Connection

• Identify the power pins (VCC and GND) on the module. Refer to the product datasheet for the exact pinout.
• Connect the module to a stable DC power supply within the range of 3.3V to 15V. Ensure correct polarity.
• The typical working current is 6mA at 5V.

4.3 Output Connection

• Locate the output pin (often labeled 'OUT' or 'O').
• Connect this output to your control circuit or microcontroller's input.
• The module provides a digital output voltage of approximately 3V (2.9V-3.1V) when motion is detected. The output current is less than 10mA.

4.4 Placement Considerations

• The module detects human movement radially within a range of 0.2 to 7 meters.
• Avoid placing the module directly facing large metallic objects or surfaces that could cause significant reflections, which might interfere with detection.
• The module can be housed in plastic enclosures without significant performance degradation.

5. Operating Instructions

The HLK-LD101 module operates by emitting microwave signals and detecting changes in the reflected signal frequency (Doppler effect) caused by moving objects, such as humans.

1. Power On: After connecting the power supply, the module requires approximately 15 seconds (typical) to stabilize. During this period, avoid movement in the detection area to prevent false triggers.
2. Detection: Once stable, the module continuously monitors its detection zone. When human movement is detected, the output pin will transition to a high state (approx. 3V).
3. Output Signal: The output signal can be used to trigger external devices, such as lights, alarms, or to provide input to a microcontroller for further processing.
4. Parameter Adjustment: The module supports serial port functions for advanced users to adjust parameters like sensitivity or detection range. Refer to the detailed product datasheet for serial communication protocols and commands.

6. Maintenance

The HLK-LD101 radar module is designed for low maintenance. Adhere to the following guidelines:

• Cleaning: Keep the module free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using liquids or abrasive cleaners.
• Environment: Operate the module within its specified temperature range (-20 ℃ to +60 ℃). Avoid exposure to extreme humidity or direct water contact.
• Physical Damage: Handle the module with care to prevent physical damage to the PCB or components.
