Features and Specifications:
-
Operating Frequency: 5 GHz
- The HLK-LD012-5G sensor operates at the 5 GHz frequency, which is commonly used for higher precision and reduced interference, especially in environments with dense radio frequency (RF) signals. This makes it a good choice for situations where other Wi-Fi or Bluetooth signals could interfere with lower-frequency radar sensors (like 2.4 GHz).
-
Detection Range:
- The sensor can detect motion and proximity within a certain range, which typically extends up to 5-10 meters depending on the environment. The detection range can be influenced by factors such as obstructions and environmental conditions (e.g., walls or large objects).
-
Output Type:
- The sensor generally outputs a digital signal (high/low pulse), indicating whether motion or a nearby object has been detected. This signal can be easily interfaced with microcontrollers (e.g., Arduino, Raspberry Pi) for further processing or control.
-
Applications:
- Motion Detection: Detects the presence of motion in a specific area and triggers actions, such as turning on lights or activating alarms.
- Proximity Sensing: Senses the proximity of objects or people, enabling applications like automatic doors or smart appliances.
- Distance Measurement: The module can be used in systems that require the measurement of distances or detection of objects at specific ranges.
-
Power Supply:
- Typically operates at 5V DC, and the module may have an onboard regulator for stable operation. Power consumption is generally low, making it suitable for battery-operated devices or low-power IoT applications.
-
Compact Size:
- The module is designed to be compact, making it easy to integrate into embedded systems and projects where space is a concern.
-
Low Power Consumption:
- This sensor is designed for low power consumption, which is beneficial for battery-powered applications like IoT or wearable devices that require motion sensing without draining the power supply quickly.
-
Output Sensitivity and Range:
- The output sensitivity and detection range can typically be adjusted or fine-tuned using external components (e.g., resistors or potentiometers) to optimize performance for specific applications.
