The LD2410C, a high-sensitivity 24GHz human presence sensing module developed by Hi-Link, is a groundbreaking device that has the potential to revolutionize various industries.
Utilizing advanced radar technology, it accurately detects the presence of humans in a designated area, offering a reliable and versatile solution for a wide range of applications.
Human Presence Sensing Module with Radio Waves
Offering greater accuracy than infrared (IR) sensors, this module can detect both moving and non-moving objects. Even subtle breathing movements can be detected when people are present in the room
How Does It Work?
The LD2410C employs Frequency-Modulated Continuous Wave (FMCW) radar technology to achieve its impressive capabilities. By emitting and receiving radio waves, it can measure the Doppler shift caused by the movement of human bodies, allowing it to accurately determine their presence. This technology offers several advantages over traditional motion sensors, such as infrared sensors, as it is not affected by factors like light, temperature, or dust.
Key Features and Benefits
High Sensitivity
Wide Detection Range
Low Power Consumption
