Product description

Introducing Hailingco Electronics' LD2410 mmWave Human Presence Sensors - the perfect addition to your smart home network. With Bluetooth support and compatibility with Home Assistant (they were added to Home Assistant in version 2023.02), these sensors fill the gap left by traditional PIR motion detectors that forget you're in the room if you're not moving!

These modules are highly sensitive and utilize FMCW FM continuous wave technology to detect human targets in your room. Combining radar signal processing and accurate human sensing algorithms, they achieve high precision. With a sensing distance of up to 5 meters and a distance resolution of 0.75m, these modules accurately identify human bodies in motion or at rest and calculate the distance of the target and other auxiliary information.

Whether you're using them for home automation or security applications, the LD2410B and LD2410C with Bluetooth and Home Assistant support are versatile solutions for human presence detection. If you're experiencing range issues with Bluetooth from your Home Assistant hub, we recommend using these modules with a ESPHome Bluetooth proxy.

Please note that the LD2410B and LD2410C are identical except for their form factor and pin header sizes. The LD2410B has a 1.27mm pin header, while the LD2410C has a full-size 2.54mm pin header. Customize the sensing distance range and sensitivity in different zones to suit specific application requirements using the visual configuration tools provided. Choose Hi-Link LD2410B or LD2410C mmWave Human Presence Sensors for highly accurate human presence detection in your smart home network.
