The LD2410C from High-Link solves the fundamental limitation of PIR sensors by detecting both stationary and moving humans up to 6 meters away. Using 24 GHz FMCW radar technology, this sensor identifies when someone is sitting, sleeping, or working – not just walking by.
Key breakthrough: While PIR sensors only trigger on movement, the LD2410 provides continuous occupancy detection with 0.57-meter resolution and ±60° coverage, making it ideal for smart home automation, security systems, and energy management applications where knowing if someone is actually present – not just moving – is critical.
Ready to integrate: With UART communication, Bluetooth connectivity, and dedicated configuration tools, the LD2410 easily connects to ESP32, Arduino, and other microcontrollers for immediate deployment in next-generation presence detection systems.
